CVE-2013-0221

SUSE coreutils-i18n.patch para GNU coreutils permite a atacantes dependientes del contexto provocar una denegación de servicio (caída y fallo de segmentación) a través de una cadena larga hacia el comando sort, cuando se usa el switch (1) -d o (2) -M, lo que desencadena en un desbordamiento de búfer basado en pila en la función alloca.

The coreutils package contains the core GNU utilities. It is a combination of the old GNU fileutils, sh-utils, and textutils packages. It was discovered that the sort, uniq, and join utilities did not properly restrict the use of the alloca() function. An attacker could use this flaw to crash those utilities by providing long input strings. These updated coreutils packages include numerous bug fixes and two enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.
