[***** Start DSA-1131-1 *****] DSA-1131-1 apache -- buffer overflow Date Reported: 01 Aug 2006 Affected Packages: apache Vulnerable: Yes Security database references: In the Debian bugtracking system: Bug 380231. In Mitre's CVE dictionary: CVE-2006-3747. CERT's vulnerabilities, advisories and incident notes: VU#395412. More information: Mark Dowd discovered a buffer overflow in the mod_rewrite component of apache, a versatile high-performance HTTP server. In some situations a remote attacker could exploit this to execute arbitary code. For the stable distribution (sarge) this problem has been fixed in version 1.3.33-6sarge2. For the unstable distribution (sid) this problems will be fixed shortly. We recommend that you upgrade your apache package.
