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

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


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.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
