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.
CVE-2021-41990 4 Debian, Fedoraproject, Siemens and 1 more 37 Debian Linux, Fedora, 6gk5615-0aa00-2aa2 and 34 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent by an initiator. Remote code execution cannot occur.
CVE-2021-41819 6 Debian, Fedoraproject, Opensuse and 3 more 9 Debian Linux, Fedora, Factory and 6 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
CGI::Cookie.parse in Ruby through 2.6.8 mishandles security prefixes in cookie names. This also affects the CGI gem through 0.3.0 for Ruby.
CVE-2021-41817 6 Debian, Fedoraproject, Opensuse and 3 more 9 Debian Linux, Fedora, Factory and 6 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Date.parse in the date gem through 3.2.0 for Ruby allows ReDoS (regular expression Denial of Service) via a long string. The fixed versions are 3.2.1, 3.1.2, 3.0.2, and 2.0.1.
CVE-2021-41816 2 Fedoraproject, Ruby-lang 3 Fedora, Cgi, Ruby 2026-06-17 7.5 HIGH 9.8 CRITICAL
CGI.escape_html in Ruby before 2.7.5 and 3.x before 3.0.3 has an integer overflow and resultant buffer overflow via a long string on platforms (such as Windows) where size_t and long have different numbers of bytes. This also affects the CGI gem before 0.3.1 for Ruby.
CVE-2021-41800 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2026-06-17 5.0 MEDIUM 5.3 MEDIUM
MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). Visiting Special:Contributions can sometimes result in a long running SQL query because PoolCounter protection is mishandled.
CVE-2021-41799 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2026-06-17 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). ApiQueryBacklinks (action=query&list=backlinks) can cause a full table scan.
CVE-2021-41798 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
MediaWiki before 1.36.2 allows XSS. Month related MediaWiki messages are not escaped before being used on the Special:Search results page.
CVE-2021-41773 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2026-06-17 4.3 MEDIUM 9.8 CRITICAL
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. 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 is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013.
CVE-2021-41772 3 Fedoraproject, Golang, Oracle 3 Fedora, Go, Timesten In-memory Database 2026-06-17 5.0 MEDIUM 7.5 HIGH
Go before 1.16.10 and 1.17.x before 1.17.3 allows an archive/zip Reader.Open panic via a crafted ZIP archive containing an invalid name or an empty filename field.
CVE-2021-41771 3 Debian, Fedoraproject, Golang 3 Debian Linux, Fedora, Go 2026-06-17 5.0 MEDIUM 7.5 HIGH
ImportedSymbols in debug/macho (for Open or OpenFat) in Go before 1.16.10 and 1.17.x before 1.17.3 Accesses a Memory Location After the End of a Buffer, aka an out-of-bounds slice situation.
CVE-2021-41611 2 Fedoraproject, Squid-cache 2 Fedora, Squid 2026-06-17 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote server to obtain security trust well improperly. This indication of trust may be passed along to clients, allowing access to unsafe or hijacked services.
CVE-2021-41583 3 Debian, Eduvpn, Fedoraproject 3 Debian Linux, Vpn-user-portal, Fedora 2026-06-17 9.0 HIGH 6.5 MEDIUM
vpn-user-portal (aka eduVPN or Let's Connect!) before 2.3.14, as packaged for Debian 10, Debian 11, and Fedora, allows remote authenticated users to obtain OS filesystem access, because of the interaction of QR codes with an exec that uses the -r option. This can be leveraged to obtain additional VPN access.
