| CVE-2020-16135 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-11-21 | 5.9 Medium |
| libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL. | ||||
| CVE-2020-16128 | 1 Canonical | 1 Ubuntu Linux | 2024-11-21 | 3.8 Low |
| The aptdaemon DBus interface disclosed file existence disclosure by setting Terminal/DebconfSocket properties, aka GHSL-2020-192 and GHSL-2020-196. This affected versions prior to 1.1.1+bzr982-0ubuntu34.1, 1.1.1+bzr982-0ubuntu32.3, 1.1.1+bzr982-0ubuntu19.5, 1.1.1+bzr982-0ubuntu14.5. | ||||
| CVE-2020-16123 | 1 Canonical | 1 Ubuntu Linux | 2024-11-21 | 4.4 Medium |
| An Ubuntu-specific patch in PulseAudio created a race condition where the snap policy module would fail to identify a client connection from a snap as coming from a snap if SCM_CREDENTIALS were missing, allowing the snap to connect to PulseAudio without proper confinement. This could be exploited by an attacker to expose sensitive information. Fixed in 1:13.99.3-1ubuntu2, 1:13.99.2-1ubuntu2.1, 1:13.99.1-1ubuntu3.8, 1:11.1-1ubuntu7.11, and 1:8.0-0ubuntu3.15. | ||||
| CVE-2020-16122 | 2 Canonical, Packagekit Project | 2 Ubuntu Linux, Packagekit | 2024-11-21 | 8.2 High |
| PackageKit's apt backend mistakenly treated all local debs as trusted. The apt security model is based on repository trust and not on the contents of individual files. On sites with configured PolicyKit rules this may allow users to install malicious packages. | ||||
| CVE-2020-16121 | 2 Canonical, Packagekit Project | 2 Ubuntu Linux, Packagekit | 2024-11-21 | 3.3 Low |
| PackageKit provided detailed error messages to unprivileged callers that exposed information about file presence and mimetype of files that the user would be unable to determine on its own. | ||||
| CVE-2020-16120 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 5.1 Medium |
| Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify permissions in ovl_path_open()"), 48bd024 ("ovl: switch to mounter creds in readdir") and 05acefb ("ovl: check permission to open real file"). Additionally, commits 130fdbc ("ovl: pass correct flags for opening real directory") and 292f902 ("ovl: call secutiry hook in ovl_real_ioctl()") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da ("ovl: do not fail because of O_NOATIMEi") in kernel 5.11. | ||||
| CVE-2020-16119 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-11-21 | 6.3 Medium |
| Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196. | ||||
| CVE-2020-16116 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 3.3 Low |
| In kerfuffle/jobs.cpp in KDE Ark before 20.08.0, a crafted archive can install files outside the extraction directory via ../ directory traversal. | ||||
| CVE-2020-16092 | 5 Canonical, Debian, Opensuse and 2 more | 8 Ubuntu Linux, Debian Linux, Leap and 5 more | 2024-11-21 | 3.8 Low |
| In QEMU through 5.0.0, an assertion failure can occur in the network packet processing. This issue affects the e1000e and vmxnet3 network devices. A malicious guest user/process could use this flaw to abort the QEMU process on the host, resulting in a denial of service condition in net_tx_pkt_add_raw_fragment in hw/net/net_tx_pkt.c. | ||||
| CVE-2020-15900 | 3 Artifex, Canonical, Opensuse | 3 Ghostscript, Ubuntu Linux, Leap | 2024-11-21 | 9.8 Critical |
| A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b. | ||||
| CVE-2020-15890 | 4 Canonical, Debian, Luajit and 1 more | 4 Ubuntu Linux, Debian Linux, Luajit and 1 more | 2024-11-21 | 7.5 High |
| LuaJit through 2.1.0-beta3 has an out-of-bounds read because __gc handler frame traversal is mishandled. | ||||
| CVE-2020-15863 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2024-11-21 | 5.3 Medium |
| hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. | ||||
| CVE-2020-15862 | 4 Canonical, Net-snmp, Netapp and 1 more | 11 Ubuntu Linux, Net-snmp, Cloud Backup and 8 more | 2024-11-21 | 7.8 High |
| Net-SNMP through 5.8 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB provides the ability to run arbitrary commands as root. | ||||
| CVE-2020-15861 | 3 Canonical, Net-snmp, Netapp | 5 Ubuntu Linux, Net-snmp, Cloud Backup and 2 more | 2024-11-21 | 7.8 High |
| Net-SNMP through 5.7.3 allows Escalation of Privileges because of UNIX symbolic link (symlink) following. | ||||
| CVE-2020-15811 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Splitting attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the browser cache and any downstream caches with content from an arbitrary source. Squid uses a string search instead of parsing the Transfer-Encoding header to find chunked encoding. This allows an attacker to hide a second request inside Transfer-Encoding: it is interpreted by Squid as chunked and split out into a second request delivered upstream. Squid will then deliver two distinct responses to the client, corrupting any downstream caches. | ||||
| CVE-2020-15810 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream. | ||||
| CVE-2020-15780 | 4 Canonical, Linux, Opensuse and 1 more | 6 Ubuntu Linux, Linux Kernel, Leap and 3 more | 2024-11-21 | 6.7 Medium |
| An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30. | ||||
| CVE-2020-15710 | 2 Canonical, Pulseaudio Project | 2 Ubuntu Linux, Pulseaudio | 2024-11-21 | 5.3 Medium |
| Potential double free in Bluez 5 module of PulseAudio could allow a local attacker to leak memory or crash the program. The modargs variable may be freed twice in the fail condition in src/modules/bluetooth/module-bluez5-device.c and src/modules/bluetooth/module-bluez5-device.c. Fixed in 1:8.0-0ubuntu3.14. | ||||
| CVE-2020-15709 | 1 Canonical | 1 Add-apt-repository | 2024-11-21 | 5.5 Medium |
| Versions of add-apt-repository before 0.98.9.2, 0.96.24.32.14, 0.96.20.10, and 0.92.37.8ubuntu0.1~esm1, printed a PPA (personal package archive) description to the terminal as-is, which allowed PPA owners to provide ANSI terminal escapes to modify terminal contents in unexpected ways. | ||||
| CVE-2020-15708 | 1 Canonical | 1 Ubuntu Linux | 2024-11-21 | 9.3 Critical |
| Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code. | ||||
