Multiple signedness errors (mixed signed and unsigned numbers) in the I/O functions of rsync 2.4.6, 2.3.2, and other versions allow remote attackers to cause a denial of service and execute arbitrary code in the rsync client or server.

rsync, when running in daemon mode, does not properly call setgroups before dropping privileges, which could provide supplemental group privileges to local users, who could then read certain files that would otherwise be disallowed.

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.

rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot, which allows remote attackers to write files outside of the module's path.

Directory traversal vulnerability in the sanitize_path function in util.c for rsync 2.6.2 and earlier, when chroot is disabled, allows attackers to read or write certain files.

Integer overflow in the receive_xattr function in the extended attributes patch (xattr.c) for rsync before 2.6.8 might allow attackers to execute arbitrary code via crafted extended attributes that trigger a buffer overflow.

Multiple off-by-one errors in the sender.c in rsync 2.6.9 might allow remote attackers to execute arbitrary code via directory names that are not properly handled when calling the f_name function.

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.

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.

rsync 3.x before 3.0.8, when certain recursion, deletion, and ownership options are used, allows remote rsync servers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via malformed data.

rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions.

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 mali...
