Unspecified vulnerability in the expand_stack function in grsecurity PaX allows local users to gain privileges via unspecified vectors. 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. As of 20070120, the original researcher has released demonstration code ** DISPUTADA ** Vulnerabilidad no especificada en la función expand_stack en grsecurity PaX permite a usuarios locales obtener privilegios a través de vectores no especificados. NOTA: el desarrollador grsecurity ha disputado este problema, diciendo que 'la función donde dicen que está la vulnerabilidad es una función insignificante, que puede ser, y ha sido, fácilmente comprobada por cualquier supuesta vulnerabilidad.' • https://www.exploit-db.com/exploits/29446 http://forums.grsecurity.net/viewtopic.php?t=1646 http://grsecurity.net/news.php#digitalfud http://osvdb.org/32727 http://secunia.com/advisories/23713 http://securitytracker.com/id?1017509 http://www.digitalarmaments.com/news_news.shtml http://www.digitalarmaments.com/pre2007-00018659.html http://www.securityfocus.com/archive/1/456626/100/0/threaded http://www.securityfocus.com/archive/1/456722/100/0/threaded http://www.securityfocus. •
