CVE-2021-3998 2 Gnu, Netapp 12 Glibc, H300s, H300s Firmware and 9 more 2024-11-21 N/A 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-2021-3981 2 Fedoraproject, Gnu 2 Fedora, Grub2 2024-11-21 2.1 LOW 3.3 LOW
A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.
CVE-2021-3826 2 Fedoraproject, Gnu 2 Fedora, Gcc 2024-11-21 N/A 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 12 Grub2, Codeready Linux Builder, Developer Tools and 9 more 2024-11-21 4.4 MEDIUM 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 13 Grub2, Ontap Select Deploy Administration Utility, Codeready Linux Builder and 10 more 2024-11-21 6.9 MEDIUM 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 14 Fedora, Grub2, Ontap Select Deploy Administration Utility and 11 more 2024-11-21 4.4 MEDIUM 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 5.0 MEDIUM 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 10.0 HIGH 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 4.4 MEDIUM 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 5 Debian, Fujitsu, Gnu and 2 more 17 Debian Linux, M10-1, M10-1 Firmware and 14 more 2024-11-21 5.0 MEDIUM 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 6.8 MEDIUM 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 6.8 MEDIUM 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 6.8 MEDIUM 8.8 HIGH
An issue was discovered in libredwg through v0.10.1.3751. dwg_free_MATERIAL_private() in dwg.spec has a double free.
CVE-2021-39527 1 Gnu 1 Libredwg 2024-11-21 6.8 MEDIUM 8.8 HIGH
An issue was discovered in libredwg through v0.10.1.3751. appinfo_private() in decode.c has a heap-based buffer overflow.
CVE-2021-39525 1 Gnu 1 Libredwg 2024-11-21 6.8 MEDIUM 8.8 HIGH
An issue was discovered in libredwg through v0.10.1.3751. bit_read_fixed() in bits.c has a heap-based buffer overflow.
CVE-2021-39523 1 Gnu 1 Libredwg 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
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 6.8 MEDIUM 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 4.3 MEDIUM 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 5.0 MEDIUM 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 1 Gnu 1 Cpio 2024-11-21 6.8 MEDIUM 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.
