Summary
bzip2 is a freely available, high-quality data compressor. It provides both
standalone compression and decompression utilities, as well as a shared
library for use with other programs.
An integer overflow flaw was discovered in the bzip2 decompression routine.
This issue could, when decompressing malformed archives, cause bzip2, or an
application linked against the libbz2 library, to crash or, potentially,
execute arbitrary code. (CVE-2010-0405)
Users of bzip2 should upgrade to these updated packages, which contain a
backported patch to resolve this issue. All running applications using the
libbz2 library must be restarted for the update to take effect.
