Package : ncompress Vulnerability : integer underflow Problem type : local Debian-specific: no CVE Id : CVE-2010-0001
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.
For the stable distribution (lenny), this problem has been fixed in version 4.2.4.2-1+lenny1.
For the testing (squeeze) and unstable (sid) distribution, this problem has been fixed in version 4.2.4.3-1.
We recommend that you upgrade your ncompress package.
