The key_replace_session_keyring function in security/keys/process_keys.c in the Linux kernel before 2.6.39.1 does not initialize a certain structure member, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function, a different vulnerability than CVE-2010-2960. La función key_replace_session_keyring en security/keys/process_keys.c en el kernel de Linux anterior a v2.6.39.1 no inicializa un determinado miembro de una 'struct', lo que permite a usuarios locales causar una denegación de servicio (puntero a NULL y OOPS) o posiblemente tener un impacto no especificado a través del argumento KEYCTL_SESSION_TO_PARENT a la función keyctl. Se trata de una vulnerabilidad diferente a CVE-2010-2960. • http://alt.swiecki.net/linux_kernel/sys_open-kmem_cache_alloc-2.6.39-rc4.txt http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f7285b5d631fd6096b11c6af0058ed3a2b30ef4e http://securityreason.com/securityalert/8371 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39.1 http://www.openwall.com/lists/oss-security/2011/06/03/2 http://www.openwall.com/lists/oss-security/2011/06/06/2 https://lkml.org/lkml/2011/5/23/199 https:&#x • CWE-476: NULL Pointer Dereference •

The skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload (GRO) is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service (system crash) via crafted network traffic. La función skb_gro_header_slow en includelinuxnetdevice.h en kernel de Linux anteriores a v2.6.39.4, cuando está activada la opción Generic Receive Offload (GRO), reinicia ciertos campos en situaciones incorrectas, lo que permite producir una denegación de servicio (caída del sistema) mediante una tráfico de red manipulado. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=17dd759c67f21e34f2156abcf415e1f60605a188 http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://openwall.com/lists/oss-security/2011/07/28/13 http://openwall.com/lists/oss-security/2011/07/29/1 http://securitytracker.com/id?1025876 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39.4 http://www.redhat.com/support/errata/RHSA-2011-1321.html http://www.securityfocus.com/bid&# • CWE-20: Improper Input Validation •
