Disclosure Date


bzip2 contains an integer overflow condition in the decompress functionality. The issue is due to the 'BZ2_decompress()' function in decompress.c not validating user-supplied input when decompressing files. With a specially crafted compressed file, a context-dependent attacker can cause an integer overflow, resulting in a denial of service or potentially execution of arbitrary code.
