Subject: MDKSA-2005:091 - Updated bzip2 packages fix
multiple vulnerabilities
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
_______________________________________________________________________
Mandriva Linux Security Update Advisory
_______________________________________________________________________
Package name: bzip2
Advisory ID: MDKSA-2005:091
Date: May 18th, 2005
Affected versions: 10.0, 10.1, 10.2, Corporate 3.0,
Corporate Server 2.1
______________________________________________________________________
Problem Description:
A race condition in the file permission restore code of bunzip2 was
discovered by Imran Ghory. While a user was decompressing a file, a
local attacker with write permissions to the directory containing the
compressed file could replace the target file with a hard link which
would cause bunzip2 to restore the file permissions of the original
file to the hard link target. This could be exploited to gain read or
write access to files of other users (CAN-2005-0953).
A vulnerability was found where specially crafted bzip2 archives would
cause an infinite loop in the decompressor, resulting in an
indefinitively large output file (also known as a "decompression
bomb"). This could be exploited to cause a Denial of Service attack
on the host computer due to disk space exhaustion (CAN-2005-1260).
The provided packages have been patched to correct these issues.
