CVE-2021-3999 | 4 Debian, Gnu, Netapp and 1 more | 16 Debian Linux, Glibc, E-series Performance Analyzer and 13 more | 2024-11-21 | 7.8 High |
A flaw was found in glibc. An off-by-one buffer overflow and underflow in getcwd() may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and size passed to getcwd() in a setuid program could use this flaw to potentially execute arbitrary code and escalate their privileges on the system. | ||||
CVE-2021-3998 | 2 Gnu, Netapp | 12 Glibc, H300s, H300s Firmware and 9 more | 2024-11-21 | 7.5 High |
A flaw was found in glibc. The realpath() function can mistakenly return an unexpected value, potentially leading to information leakage and disclosure of sensitive data. | ||||
CVE-2021-3826 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Gcc, Enterprise Linux and 1 more | 2024-11-21 | 6.5 Medium |
Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol. | ||||
CVE-2021-3697 | 2 Gnu, Redhat | 14 Grub2, Codeready Linux Builder, Developer Tools and 11 more | 2024-11-21 | 7.0 High |
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. | ||||
CVE-2021-3696 | 3 Gnu, Netapp, Redhat | 15 Grub2, Ontap Select Deploy Administration Utility, Codeready Linux Builder and 12 more | 2024-11-21 | 4.5 Medium |
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. | ||||
CVE-2021-3695 | 4 Fedoraproject, Gnu, Netapp and 1 more | 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more | 2024-11-21 | 4.5 Medium |
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. | ||||
CVE-2021-3530 | 2 Gnu, Netapp | 2 Binutils, Ontap Select Deploy Administration Utility | 2024-11-21 | 7.5 High |
A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash. | ||||
CVE-2021-3466 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Libmicrohttpd, Enterprise Linux | 2024-11-21 | 9.8 Critical |
A flaw was found in libmicrohttpd. A missing bounds check in the post_process_urlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Only version 0.9.70 is vulnerable. | ||||
CVE-2021-3418 | 1 Gnu | 1 Grub2 | 2024-11-21 | 6.4 Medium |
If certificates that signed grub are installed into db, grub can be booted directly. It will then boot any kernel without signature validation. The booted kernel will think it was booted in secureboot mode and will implement lockdown, yet it could have been tampered. This flaw is a reintroduction of CVE-2020-15705 and only affects grub2 versions prior to 2.06 and upstream and distributions using the shim_lock mechanism. | ||||
CVE-2021-3326 | 6 Debian, Fujitsu, Gnu and 3 more | 18 Debian Linux, M10-1, M10-1 Firmware and 15 more | 2024-11-21 | 7.5 High |
The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid input sequences in the ISO-2022-JP-3 encoding, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | ||||
CVE-2021-39537 | 2 Apple, Gnu | 3 Mac Os X, Macos, Ncurses | 2024-11-21 | 8.8 High |
An issue was discovered in ncurses through v6.2-1. _nc_captoinfo in captoinfo.c has a heap-based buffer overflow. | ||||
CVE-2021-39530 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
An issue was discovered in libredwg through v0.10.1.3751. bit_wcs2nlen() in bits.c has a heap-based buffer overflow. | ||||
CVE-2021-39528 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |

An issue was discovered in libredwg through v0.10.1.3751. A NULL pointer dereference exists in the function check_POLYLINE_handles() located in decode.c. It allows an attacker to cause Denial of Service. | ||||
CVE-2021-39522 | 1 Gnu | 1 Libredwg | 2024-11-21 | 8.8 High |
An issue was discovered in libredwg through v0.10.1.3751. bit_wcs2len() in bits.c has a heap-based buffer overflow. | ||||
CVE-2021-39521 | 1 Gnu | 1 Libredwg | 2024-11-21 | 6.5 Medium |
An issue was discovered in libredwg through v0.10.1.3751. A NULL pointer dereference exists in the function bit_read_BB() located in bits.c. It allows an attacker to cause Denial of Service. | ||||
CVE-2021-38604 | 3 Fedoraproject, Gnu, Oracle | 8 Fedora, Glibc, Communications Cloud Native Core Binding Support Function and 5 more | 2024-11-21 | 7.5 High |
In librt in the GNU C Library (aka glibc) through 2.34, sysdeps/unix/sysv/linux/mq_notify.c mishandles certain NOTIFY_REMOVED data, leading to a NULL pointer dereference. NOTE: this vulnerability was introduced as a side effect of the CVE-2021-33574 fix. | ||||
CVE-2021-38185 | 2 Gnu, Redhat | 2 Cpio, Enterprise Linux | 2024-11-21 | 7.8 High |
GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data. |
