Ubuntu 6.06 LTS / 6.10 / 7.04 : rsync vulnerability (USN-500-1)

medium Nessus Plugin ID 28103

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Sebastian Krahmer discovered that rsync contained an off-by-one miscalculation when handling certain file paths. By creating a specially crafted tree of files and tricking an rsync server into processing them, a remote attacker could write a single NULL to stack memory, possibly leading to arbitrary code execution.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected rsync package.
