CVE-2010-3873

La implementación de X.25 en el kernel de Linux anterior a v2.6.36.2 no analiza adecuadamente las instalaciones, lo que permite a atacantes remotos provocar una denegación de servicio (daños en el montón de memoria y el pánico) o posiblemente tener un impacto no especificado a través de formato incorrecto (1) X25_FAC_CALLING_AE o (2) Los datos X25_FAC_CALLED_AE, relacionados con net/x25/x25_facilities.c y net/x25/x25_in.c, una vulnerabilidad diferente de CVE-2010-4164.

Tavis Ormandy discovered that the Linux kernel did not properly implement exception fixup. A local attacker could exploit this to crash the kernel, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that the Linux kernel X.25 implementation incorrectly parsed facilities. A remote attacker could exploit this to crash the kernel, leading to a denial of service. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Vasiliy Kulikov discovered that the Linux kernel sockets implementation did not properly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service. Various other issues were also addressed.
