Red Hat Security Advisory 2012-0308-03
» ‎ Packet Storm Security Advisories

Red Hat Security Advisory 2012-0308-03 - BusyBox provides a single binary that includes versions of a large number of system commands, including a shell. This can be very useful for recovering from certain types of system failures, particularly those involving broken shared libraries. A buffer underflow flaw was found in the way the uncompress utility of BusyBox expanded certain archive files compressed using Lempel-Ziv compression. If a user were tricked into expanding a specially-crafted archive file with uncompress, it could cause BusyBox to crash or, potentially, execute arbitrary code with the privileges of the user running BusyBox.

» ‎ Packet Storm Security Recent Files

FreeBSD Security Advisory - The bzip2/bunzip2 utilities and the libbz2 library compress and decompress files using an algorithm based on the Burrows-Wheeler transform. They are generally slower than Lempel-Ziv compressors such as gzip, but usually provide a greater compression ratio. When decompressing data, the run-length encoded values are not adequately sanity-checked, allowing for an integer overflow.

Debian Linux Security Advisory 2074-1 - Aki Helin discovered an integer underflow in ncompress, the original Lempel-Ziv compress/uncompress programs. This could lead to the execution of arbitrary code when trying to decompress a crafted LZW compressed gzip archive.
