CVE-2026-70463 1 Samba 1 Rsync 2026-10-24 N/A 8.1 HIGH
rsync 3.1.0 before 3.5.0 contains an authorization bypass in auth users directive parsing. The auth users parser uses comma-only tokenization when splitting the user list, which fails to correctly handle entries of the form @Group Name where the group name contains a space. The space within the group name causes the parser to split the entry at the space boundary, discarding the deny rule associated with the group. An authenticated user whose username or group membership would be denied by an @Group Name auth users entry can connect to a restricted module because the deny rule is silently discarded during parsing.
CVE-2024-12088 8 Almalinux, Archlinux, Gentoo and 5 more 20 Almalinux, Arch Linux, Linux and 17 more 2026-10-21 N/A 6.5 MEDIUM
A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly verify if a symbolic link destination sent from the server contains another symbolic link within it. This results in a path traversal vulnerability, which may lead to arbitrary file write outside the desired directory.
CVE-2024-12087 8 Almalinux, Archlinux, Gentoo and 5 more 18 Almalinux, Arch Linux, Linux and 15 more 2026-10-21 N/A 6.5 MEDIUM
A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client.
CVE-2024-12084 8 Almalinux, Archlinux, Gentoo and 5 more 8 Almalinux, Arch Linux, Linux and 5 more 2026-10-21 N/A 9.8 CRITICAL
A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.
CVE-2026-58224 2 Redhat, Samba 2 Enterprise Linux, Samba 2026-10-21 N/A 6.5 MEDIUM
A flaw was found in Samba's CTDB, the clustered database service used by Samba. Insufficient integrity validation of received CTDB protocol packets allows malformed packets containing invalid field lengths, improperly terminated strings, or inconsistent packet sizes to be processed without adequate bounds checking. A remote attacker with access to the CTDB private network may trigger a denial of service through process crashes or excessive memory consumption and, in limited cases, disclose adjacent memory contents.
CVE-2026-2340 2 Redhat, Samba 3 Enterprise Linux, Openshift Container Platform, Samba 2026-10-15 N/A 6.5 MEDIUM
A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file.
CVE-2022-42898 3 Heimdal Project, Mit, Samba 3 Heimdal, Kerberos 5, Samba 2026-10-14 N/A 8.8 HIGH
PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has "a similar bug."
CVE-2024-12085 8 Almalinux, Archlinux, Gentoo and 5 more 22 Almalinux, Arch Linux, Linux and 19 more 2026-10-13 N/A 7.5 HIGH
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
CVE-2000-0939 1 Samba 1 Samba 2026-09-23 5.0 MEDIUM N/A
Samba Web Administration Tool (SWAT) in Samba 2.0.7 allows remote attackers to cause a denial of service by repeatedly submitting a nonstandard URL in the GET HTTP request and forcing it to restart.
CVE-2000-0938 1 Samba 1 Samba 2026-09-23 5.0 MEDIUM N/A
Samba Web Administration Tool (SWAT) in Samba 2.0.7 supplies a different error message when a valid username is provided versus an invalid name, which allows remote attackers to identify valid users on the server.
CVE-2000-0935 1 Samba 1 Samba 2026-09-23 7.2 HIGH N/A
Samba Web Administration Tool (SWAT) in Samba 2.0.7 allows local users to overwrite arbitrary files via a symlink attack on the cgi.log file.
CVE-2000-0936 1 Samba 1 Samba 2026-09-23 2.1 LOW N/A
Samba Web Administration Tool (SWAT) in Samba 2.0.7 installs the cgi.log logging file with world readable permissions, which allows local users to read sensitive information such as user names and passwords.
CVE-2026-43618 1 Samba 1 Rsync 2026-09-01 N/A 8.1 HIGH
Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended buffer bounds. Attackers can exploit this vulnerability to disclose process memory contents including environment variables, passwords, heap and stack data, and library memory pointers, significantly reducing ASLR effectiveness and facilitating further exploitation.
CVE-2026-4480 2 Redhat, Samba 3 Enterprise Linux, Openshift Container Platform, Samba 2026-09-01 N/A 9.0 CRITICAL
A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system.
CVE-2025-0620 1 Samba 1 Samba 2026-08-31 N/A 4.9 MEDIUM
A flaw was found in Samba. The smbd service daemon does not pick up group membership changes when re-authenticating an expired SMB session. This issue can expose file shares until clients disconnect and then connect again.
CVE-2024-12086 8 Almalinux, Archlinux, Gentoo and 5 more 9 Almalinux, Arch Linux, Linux and 6 more 2026-08-21 N/A 6.1 MEDIUM
A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file from the client's machine. This issue occurs when files are being copied from a client to a server. During this process, the rsync server will send checksums of local data to the client to compare with in order to determine what data needs to be sent to the server. By sending specially constructed checksum values for arbitrary files, an attacker may be able to reconstruct the data of those files byte-by-byte based on the responses from the client.
CVE-2026-29518 1 Samba 1 Rsync 2026-08-19 N/A 7.0 HIGH
Rsync versions before 3.4.3 contain a time-of-check to time-of-use (TOCTOU) race condition in daemon file handling that allows attackers to redirect file writes outside intended directories by replacing parent directory components with symbolic links. Attackers with write access to a module path can exploit this race condition to create or overwrite arbitrary files, potentially modifying sensitive system files and achieving privilege escalation when the daemon runs with elevated privileges. This vulnerability can only be triggered if the chroot setting is false.
CVE-2022-38023 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2026-08-10 N/A 8.1 HIGH
Netlogon RPC Elevation of Privilege Vulnerability
CVE-2022-37967 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2026-08-10 N/A 7.2 HIGH
Windows Kerberos Elevation of Privilege Vulnerability
CVE-2022-37966 4 Fedoraproject, Microsoft, Netapp and 1 more 9 Fedora, Windows Server 2008, Windows Server 2012 and 6 more 2026-08-10 N/A 8.1 HIGH
Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability
