librsync before 1.0.0 uses a truncated MD4 checksum to match blocks, which makes it easier for remote attackers to modify transmitted data via a birthday attack.

rsync 3.1.1 allows remote attackers to write to arbitrary files via a symlink attack on a file in the synchronization path.

The check_secret function in authenticate.c in rsync 3.1.0 and earlier allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a user name which does not exist in the secrets file.

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...

sample.sh in maildirsync 1.1 allows local users to append data to arbitrary files via a symlink attack on a /tmp/maildirsync-*.#####.log temporary file.

Buffer overflow in rsync 2.6.9 to 3.0.1, with extended attribute (xattr) support enabled, might allow remote attackers to execute arbitrary code via unknown vectors.

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)...

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...

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.

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.
