CVE-2015-3258 – cups-filters: texttopdf heap-based buffer overflow

https://notcve.org/view.php?id=CVE-2015-3258

Heap-based buffer overflow in the WriteProlog function in filter/texttopdf.c in texttopdf in cups-filters before 1.0.70 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a small line size in a print job. Desbordamiento del buffer basado en memoria dinámica en la función WriteProlog en filter/texttopdf.c en texttopdf en cups-filters antes del 1.0.70, que permite a atacantes remotos provocar una denegación de servcio (colapso) o la posibilidad de ejecutar código arbitrario a través de una línea larga que contiene caracteres anchos en una tarea de impresión. A heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use this flaw to crash texttopdf or, possibly, execute arbitrary code with the privileges of the "lp" user. • http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7363 http://lists.opensuse.org/opensuse-updates/2015-07/msg00033.html http://rhn.redhat.com/errata/RHSA-2015-2360.html http://ubuntu.com/usn/usn-2659-1 http://www.debian.org/security/2015/dsa-3303 http://www.openwall.com/lists/oss-security/2015/06/26/4 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/75436 https://bugzilla.redhat.com/s • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
