CVE-2024-12084 [CRITICAL] CWE-122 CVE-2024-12084: A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handl 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-2024-12085 [HIGH] CWE-908 CVE-2024-12085: A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw all 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-2024-12087 [HIGH] CWE-22 CVE-2024-12087: A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursi 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 o

CVE-2024-12088 [HIGH] CWE-22 CVE-2024-12088: A flaw was found in rsync. When using the `--safe-links` option, the rsync client fails to properly 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-2026-43618 [HIGH] CWE-125 CVE-2026-43618: Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token deco 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

CVE-2003-0962 [HIGH] CVE-2003-0962: Heap-based buffer overflow in rsync before 2 Heap-based buffer overflow in rsync before 2.5.7, when running in server mode, allows remote attackers to execute arbitrary code and possibly escape the chroot jail.

CVE-2022-29154 [HIGH] CWE-20 CVE-2022-29154: An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrar An issue was discovered in rsync before 3.2.5 that allows malicious remote servers to write arbitrary files inside the directories of connecting peers. The server chooses which files/directories are sent to the client. However, the rsync client performs insufficient validation of file names. A malicious rsync server (or Man-in-The-Middle attacker) can

CVE-2018-5764 [HIGH] CVE-2018-5764: The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.

CVE-2016-9841 [CRITICAL] CVE-2016-9841: inffast inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.

CVE-2017-15994 [CRITICAL] CWE-354 CVE-2017-15994: rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for re rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.

CVE-2007-6200 [CRITICAL] CVE-2007-6200: Unspecified vulnerability in rsync before 3 Unspecified vulnerability in rsync before 3.0.0pre6, when running a writable rsync daemon, allows remote attackers to bypass exclude, exclude_from, and filter and read or write hidden files via (1) symlink, (2) partial-dir, (3) backup-dir, and unspecified (4) dest options.

CVE-2014-9512 [MEDIUM] CWE-59 CVE-2014-9512: rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in th rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in the synchronization path.

CVE-2024-12086 [MEDIUM] CWE-390 CVE-2024-12086: A flaw was found in rsync. It could allow a server to enumerate the contents of an arbitrary file fr 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

CVE-2017-16548 [CRITICAL] CWE-125 CVE-2017-16548: The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a tra The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.

CVE-2007-6199 [CRITICAL] CVE-2007-6199: rsync before 3 rsync before 3.0.0pre6, when running a writable rsync daemon that is not using chroot, allows remote attackers to access restricted files via unknown vectors that cause rsync to create a symlink that points outside of the module's hierarchy.

CVE-2016-9842 [HIGH] CVE-2016-9842: The inflateMark function in inflate The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.

CVE-2016-9840 [HIGH] rsync vulnerabilities rsync vulnerabilities It was discovered that rsync incorrectly handled pointer arithmetic in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-9840, CVE-2016-9841) It was discovered that rsync incorrectly handled vectors involving left shifts of negative integers in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of servi

Rsync improperly validates certificate with h A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in-the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using
