Ubuntu has released a security patch to correct two vulnerabilities identified in bzip2. The first flaw is due to a race condition in the file permission restore code of bunzip2, which could be exploited by local attackers to gain read/write access to files of other users. The second vulnerability occurs when processing specially crafted bzip2 archives, which may cause an infinite loop in the decompressor (DoS).
