Updated bzip2 packages are available for Mandriva Linux

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.
