The RBAC functionality in grsecurity before 2.1.11-2.6.24.5 and 2.1.11-2.4.36.2 does not enforce user_transition_deny and user_transition_allow rules for the (1) sys_setfsuid and (2) sys_setfsgid calls, which allows local users to bypass restrictions for those calls. la funcionalidad RBAC en grsecurity anterior a 2.1.11-2.6.24.5 y 2.1.11-2.4.36.2, no refuerza adecuadamente las reglas de user_transition_deny y user_transition_allow para las llamadas a (1) sys_setfsuid y (2) sys_setfsgid, lo que permite a usuarios locales evitar ciertas restricciones para esas llamadas. • http://secunia.com/advisories/29899 http://www.grsecurity.org/news.php#grsec21113 http://www.securityfocus.com/bid/28889 http://www.securitytracker.com/id?1019919 http://www.vupen.com/english/advisories/2008/1323/references https://exchange.xforce.ibmcloud.com/vulnerabilities/41952 • CWE-264: Permissions, Privileges, and Access Controls •

Unspecified vulnerability in the grsecurity patch has unspecified impact and remote attack vectors, a different vulnerability than the expand_stack vulnerability from the Digital Armaments 20070110 pre-advisory. NOTE: the grsecurity developer has disputed this issue, stating that "the function they claim the vulnerability to be in is a trivial function, which can, and has been, easily checked for any supposed vulnerabilities." The developer also cites a past disclosure that was not proven ** EN DISPUTA ** La vulnerabilidad no especificada en el parche grsecurity tiene un impacto no especificado y vectores de ataque remoto, una vulnerabilidad diferente a la vulnerabilidad expand_stack del pre-asesor Digital Armaments 20070110. NOTA: el desarrollador de grsecurity ha impugnado este problema, afirmando que "la función en la que afirman que está la vulnerabilidad es una función trivial, que puede, y ha sido, fácilmente comprobada por cualquier supuesta vulnerabilidad". El desarrollador también cita una divulgación anterior que no fue probada. • http://forums.grsecurity.net/viewtopic.php?t=1646 http://grsecurity.net/news.php#digitalfud http://www.digitalarmaments.com/news_news.shtml •
