CVE-2010-3880

net/ipv4/inet_diag.c en el kernel Linux, en versiones anteriores a la 2.6.37-rc2, no audita apropiadamente el bytecode INET_DIAG, lo que permite a atacantes locales provocar una denegación de servicio (bucle infinito del kernel) mediante instrucciones INET_DIAG_REQ_BYTECODE debidamente modificadas en un mensaje netlink que contiene múltiples elementos de atributos, como se ha demostrado por las intrucciones INET_DIAG_BC_JMP.

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.
