CVE-2021-42612 2 Fedoraproject, Halibut Project 2 Fedora, Halibut 2026-06-17 6.8 MEDIUM 7.8 HIGH
A use after free in cleanup_index in index.c in Halibut 1.2 allows an attacker to cause a segmentation fault or possibly have other unspecified impact via a crafted text document.
CVE-2021-42574 3 Fedoraproject, Starwindsoftware, Unicode 3 Fedora, Starwind Virtual San, Unicode 2026-06-17 5.1 MEDIUM 8.3 HIGH
An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the following alternative approach to presenting this concern. An issue is noted in the nature of international text that can affect applications that implement support for The Unicode Standard and the Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-right and right-to-left characters, the visual order of tokens may be different from their logical order. Additionally, control characters needed to fully support the requirements of bidirectional text can further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such that the ordering of tokens perceived by human reviewers does not match what will be processed by a compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

A use-after-free in Busybox's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the getvar_i function
CVE-2021-42377 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2026-06-17 6.8 MEDIUM 9.8 CRITICAL
An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may be used for remote code execution under rare conditions of filtered command input.
CVE-2021-42376 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2026-06-17 1.9 LOW 5.5 MEDIUM
A NULL pointer dereference in Busybox's hush applet leads to denial of service when processing a crafted shell command, due to missing validation after a \x03 delimiter character. This may be used for DoS under very rare conditions of filtered command input.
CVE-2021-42375 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2026-06-17 1.9 LOW 5.5 MEDIUM
An incorrect handling of a special element in Busybox's ash applet leads to denial of service when processing a crafted shell command, due to the shell mistaking specific characters for reserved characters. This may be used for DoS under rare conditions of filtered command input.
CVE-2021-42374 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2026-06-17 3.3 LOW 5.3 MEDIUM
An out-of-bounds heap read in Busybox's unlzma applet leads to information leak and denial of service when crafted LZMA-compressed input is decompressed. This can be triggered by any applet/format that
CVE-2021-42373 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2026-06-17 2.1 LOW 5.5 MEDIUM
A NULL pointer dereference in Busybox's man applet leads to denial of service when a section name is supplied but no page argument is given
CVE-2021-42327 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2026-06-17 4.6 MEDIUM 6.7 MEDIUM
dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.
CVE-2021-42072 2 Barrier Project, Fedoraproject 2 Barrier, Fedora 2026-06-17 6.5 MEDIUM 8.8 HIGH
An issue was discovered in Barrier before 2.4.0. The barriers component (aka the server-side implementation of Barrier) does not sufficiently verify the identify of connecting clients. Clients can thus exploit weaknesses in the provided protocol to cause denial-of-service or stage further attacks that could lead to information leaks or integrity corruption.
CVE-2021-42013 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Cloud Backup and 3 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions.
CVE-2021-41991 4 Debian, Fedoraproject, Siemens and 1 more 46 Debian Linux, Fedora, Cp 1543-1 and 43 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.
