-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-2927-1 security@xxxxxxxxxx http://www.debian.org/security/ Salvatore Bonaccorso May 13, 2014 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : libxfont CVE ID : CVE-2014-0209 CVE-2014-0210 CVE-2014-0211 Ilja van Sprundel of IOActive discovered several security issues in the X.Org libXfont library, which may allow a local, authenticated user to attempt to raise privileges; or a remote attacker who can control the font server to attempt to execute code with the privileges of the X server. CVE-2014-0209 Integer overflow of allocations in font metadata file parsing could allow a local user who is already authenticated to the X server to overwrite other memory in the heap. CVE-2014-0210 libxfont does not validate length fields when parsing xfs protocol replies allowing to write past the bounds of allocated memory when storing the returned data from the font server. CVE-2014-0211 Integer overflows calculating memory needs for xfs replies could result in allocating too little memory and then writing the returned data from the font server past the end of the allocated buffer. For the oldstable distribution (squeeze), these problems have been fixed in version 1:1.4.1-5. For the stable distribution (wheezy), these problems have been fixed in version 1:1.4.5-4. For the unstable distribution (sid), these problems have been fixed in version 1:1.4.7-2. We recommend that you upgrade your libxfont packages.
