https://notcve.org/view.php?id=CVE-2009-1894
Race condition in PulseAudio 0.9.9, 0.9.10, and 0.9.14 allows local users to gain privileges via vectors involving creation of a hard link, related to the application setting LD_BIND_NOW to 1, and then calling execv on the target of the /proc/self/exe symlink. Condición de carrera en PulseAudio v0.9.9, v0.9.10, y v0.9.14 permite a usuarios locales conseguir privilegios a través de vectores que implican la creación de "hard links", relativo a fijar la configuración de LD_BIND_NOW a 1, y entonces, llamar a execv con el objetivo /proc/self/exe symlink. • https://www.exploit-db.com/exploits/9208 https://www.exploit-db.com/exploits/9207 http://blog.cr0.org/2009/07/old-school-local-root-vulnerability-in.html http://secunia.com/advisories/35868 http://secunia.com/advisories/35886 http://secunia.com/advisories/35896 http://security.gentoo.org/glsa/glsa-200907-13.xml http://taviso.decsystem.org/research.html http://www.akitasecurity.nl/advisory.php?id=AK20090602 http://www.debian.org/security/2009/dsa-1838 http://www.mand • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
