| CVE-2022-1012 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Rhel E4s and 2 more | 2024-11-21 | 8.2 High |
| A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem. | ||||
| CVE-2022-0778 | 8 Debian, Fedoraproject, Mariadb and 5 more | 25 Debian Linux, Fedora, Mariadb and 22 more | 2024-11-21 | 7.5 High |
| The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has invalid explicit curve parameters. Since certificate parsing happens prior to verification of the certificate signature, any process that parses an externally supplied certificate may thus be subject to a denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients consuming server certificates - TLS servers consuming client certificates - Hosting providers taking certificates or private keys from customers - Certificate authorities parsing certification requests from subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate which makes it slightly harder to trigger the infinite loop. However any operation which requires the public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-signed certificate to trigger the loop during verification of the certificate signature. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the 15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected 1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). | ||||
| CVE-2022-0566 | 2 Mozilla, Redhat | 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more | 2024-11-21 | 8.8 High |
| It may be possible for an attacker to craft an email message that causes Thunderbird to perform an out-of-bounds write of one byte when processing the message. This vulnerability affects Thunderbird < 91.6.1. | ||||
| CVE-2022-0492 | 6 Canonical, Debian, Fedoraproject and 3 more | 36 Ubuntu Linux, Debian Linux, Fedora and 33 more | 2024-11-21 | 7.8 High |
| A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. | ||||
| CVE-2022-0435 | 5 Fedoraproject, Linux, Netapp and 2 more | 40 Fedora, Linux Kernel, H300e and 37 more | 2024-11-21 | 8.8 High |
| A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. | ||||
| CVE-2022-0330 | 4 Fedoraproject, Linux, Netapp and 1 more | 52 Fedora, Linux Kernel, H300e and 49 more | 2024-11-21 | 7.8 High |
| A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. | ||||
| CVE-2021-4155 | 2 Linux, Redhat | 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more | 2024-11-21 | 5.5 Medium |
| A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. | ||||
| CVE-2021-4140 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 10.0 Critical |
| It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. | ||||
| CVE-2021-4129 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 9.8 Critical |
| Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith, Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 95, Firefox ESR < 91.4.0, and Thunderbird < 91.4.0. | ||||
| CVE-2021-4104 | 4 Apache, Fedoraproject, Oracle and 1 more | 59 Log4j, Fedora, Advanced Supply Chain Planning and 56 more | 2024-11-21 | 7.5 High |
| JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. | ||||
| CVE-2021-4083 | 5 Debian, Linux, Netapp and 2 more | 30 Debian Linux, Linux Kernel, H300e and 27 more | 2024-11-21 | 7.0 High |
| A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4. | ||||
| CVE-2021-4028 | 3 Linux, Redhat, Suse | 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more | 2024-11-21 | 7.8 High |
| A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system. | ||||
| CVE-2021-46784 | 3 Debian, Redhat, Squid-cache | 5 Debian Linux, Enterprise Linux, Rhel E4s and 2 more | 2024-11-21 | 6.5 Medium |
| In Squid 3.x through 3.5.28, 4.x through 4.17, and 5.x before 5.6, due to improper buffer management, a Denial of Service can occur when processing long Gopher server responses. | ||||
| CVE-2021-45417 | 5 Advanced Intrusion Detection Environment Project, Canonical, Debian and 2 more | 11 Advanced Intrusion Detection Environment, Ubuntu Linux, Debian Linux and 8 more | 2024-11-21 | 7.8 High |
| AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. | ||||
| CVE-2021-44790 | 8 Apache, Apple, Debian and 5 more | 20 Http Server, Mac Os X, Macos and 17 more | 2024-11-21 | 9.8 Critical |
| A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. | ||||
| CVE-2021-44533 | 4 Debian, Nodejs, Oracle and 1 more | 14 Debian Linux, Node.js, Graalvm and 11 more | 2024-11-21 | 5.3 Medium |
| Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 did not handle multi-value Relative Distinguished Names correctly. Attackers could craft certificate subjects containing a single-value Relative Distinguished Name that would be interpreted as a multi-value Relative Distinguished Name, for example, in order to inject a Common Name that would allow bypassing the certificate subject verification.Affected versions of Node.js that do not accept multi-value Relative Distinguished Names and are thus not vulnerable to such attacks themselves. However, third-party code that uses node's ambiguous presentation of certificate subjects may be vulnerable. | ||||
| CVE-2021-44532 | 4 Debian, Nodejs, Oracle and 1 more | 14 Debian Linux, Node.js, Graalvm and 11 more | 2024-11-21 | 5.3 Medium |
| Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 converts SANs (Subject Alternative Names) to a string format. It uses this string to check peer certificates against hostnames when validating connections. The string format was subject to an injection vulnerability when name constraints were used within a certificate chain, allowing the bypass of these name constraints.Versions of Node.js with the fix for this escape SANs containing the problematic characters in order to prevent the injection. This behavior can be reverted through the --security-revert command-line option. | ||||
| CVE-2021-44531 | 3 Nodejs, Oracle, Redhat | 13 Node.js, Graalvm, Mysql Cluster and 10 more | 2024-11-21 | 7.4 High |
| Accepting arbitrary Subject Alternative Name (SAN) types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js < 12.22.9, < 14.18.3, < 16.13.2, and < 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use. Additionally, when a protocol allows URI SANs, Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option. | ||||
| CVE-2021-44227 | 3 Debian, Gnu, Redhat | 5 Debian Linux, Mailman, Enterprise Linux and 2 more | 2024-11-21 | 8.8 High |
| In GNU Mailman before 2.1.38, a list member or moderator can get a CSRF token and craft an admin request (using that token) to set a new admin password or make other changes. | ||||
| CVE-2021-44142 | 6 Canonical, Debian, Fedoraproject and 3 more | 28 Ubuntu Linux, Debian Linux, Fedora and 25 more | 2024-11-21 | 8.8 High |
| The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root. | ||||
