Mandrakelinux Security Update Advisory
_______________________________________________________________________
Package name: sharutils
Advisory ID: MDKSA-2005:067
Date: April 7th, 2005
Affected versions: 10.0, 10.1, Corporate 3.0,
Corporate Server 2.1
______________________________________________________________________
Problem Description:
Shaun Colley discovered a buffer overflow in shar that was triggered
by output files (using -o) with names longer than 49 characters which
could be exploited to run arbitrary attacker-specified code.
Ulf Harnhammar discovered that shar does not check the data length
returned by the wc command.
Joey Hess discovered that unshar would create temporary files in an
insecure manner which could allow a symbolic link attack to create or
overwrite arbitrary files with the privileges of the user using unshar.
The updated packages have been patched to correct these issues.
