                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.
