Descriptions
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.
Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync did not properly handle checksum lengths. An attacker could use this issue to execute arbitrary code. Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync compared checksums with uninitialized memory. An attacker could exploit this issue to leak sensitive information. Simon Scannell, Pedro Gallegos, and Jasiel Spelman discovered that rsync incorrectly handled file checksums. A malicious server could use this to expose arbitrary client files.
