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-2024-12084 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12084.html CVE-2024-12084 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1234100 SUSE Bug 1234100 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-2024-12085 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12085.html CVE-2024-12085 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1234101 SUSE Bug 1234101 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-2024-12086 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12086.html CVE-2024-12086 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1234102 SUSE Bug 1234102 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-2024-12087 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12087.html CVE-2024-12087 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1234103 SUSE Bug 1234103 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-2024-12088 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12088.html CVE-2024-12088 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1234104 SUSE Bug 1234104 A flaw was found in rsync. This vulnerability arises from a race condition during rsync's handling of symbolic links. Rsync's default behavior when encountering symbolic links is to skip them. If an attacker replaced a regular file with a symbolic link at the right time, it was possible to bypass the default behavior and traverse symbolic links. Depending on the privileges of the rsync process, an attacker could leak sensitive information, potentially leading to privilege escalation. CVE-2024-12747 SUSE Linux Micro 6.0:rsync-3.2.7-4.1 critical To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2025/suse-su-202520122-1/ https://www.suse.com/security/cve/CVE-2024-12747.html CVE-2024-12747 https://bugzilla.suse.com/1233760 SUSE Bug 1233760 https://bugzilla.suse.com/1235475 SUSE Bug 1235475
