The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function. La función keyctl_session_to_parent en security/keys/keyctl.c en el kernel de Linux v2.6.35.4 y anteriores, espera que determinados keyrings de sesión aparezcan, lo que permite a usuarios locales provocar una denegación de servicio(deferencia a puntero nulo y caída de sistema) o posiblemente tener otro impacto sin especificar a través del argumento KEYCTL_SESSION_TO_PARENT a la función keyctl. • http://lists.opensuse.org/opensuse-security-announce/2010-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://secunia.com/advisories/41263 http://securitytracker.com/id?1024384 http://twitter.com/taviso/statuses/22777866582 http://www.openwall.com/lists/oss-security/2010/09/02/1 http://www.securityfocus.com/bid/42932 http://www.ubuntu.com/usn/USN-1000-1 http://www.vupen.com/english/advisories/2011/0298 https://bugzilla.redhat.c • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2010-2066
The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel before 2.6.35 allows local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor. La función mext_check_arguments en fs/ext4/move_extent.c en el kernel de Linux anterior a v2.6.35, permite a usuarios locales sobrescribir una archivo de solo-añadir (append-only) a través de una llamada MOVE_EXT ioctl que especifica este archivo como un donante. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1f5a81e41f8b1a782c68d3843e9ec1bfaadf7d72 http://lists.opensuse.org/opensuse-security-announce/2010-08/msg00000.html http://secunia.com/advisories/43315 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://www.openwall.com/lists/oss-security/2010/06/07/1 http://www.openwall.com/lists/oss-security/2010/06/09/1 http://www.redhat.com/support/errata/RHSA-2010-0610.html http://w •
CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 0CVE-2010-2524 – kernel: dns_resolver upcall security issue
https://notcve.org/view.php?id=CVE-2010-2524
The DNS resolution functionality in the CIFS implementation in the Linux kernel before 2.6.35, when CONFIG_CIFS_DFS_UPCALL is enabled, relies on a user's keyring for the dns_resolver upcall in the cifs.upcall userspace helper, which allows local users to spoof the results of DNS queries and perform arbitrary CIFS mounts via vectors involving an add_key call, related to a "cache stuffing" issue and MS-DFS referrals. La funcionalidad de resolución DNS en el kernel de Linux anterior a v2.6.35, cuando CONFIG_CIFS_DFS_UPCALL está activado, cuenta con el "keyring" de usuario para la "upcall" dns_resolver en el espacio de usuario cifs.upcall, lo que permite a usuarios locales secuestrar los resultados de las consultas DNS y realizar montajes (mounts) CIFS de su elección a través de vectores que involucran una llamada add_key, relacionado con un cuestión de relleno de caché (stuffing) y referencias MS-DFS. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4c0c03ca54f72fdd5912516ad0a23ec5cf01bda7 http://lists.opensuse.org/opensuse-security-announce/2010-09/msg00004.html http://marc.info/?l=oss-security&m=128072090331700&w=2 http://marc.info/?l=oss-security&m=128078387328921&w=2 http://marc.info/?l=oss-security&m=128080755321157&w=2 http://secunia.com/advisories/43315 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.35 http://www.mandr •

https://notcve.org/view.php?id=CVE-2010-2955
The cfg80211_wext_giwessid function in net/wireless/wext-compat.c in the Linux kernel before 2.6.36-rc3-next-20100831 does not properly initialize certain structure members, which allows local users to leverage an off-by-one error in the ioctl_standard_iw_point function in net/wireless/wext-core.c, and obtain potentially sensitive information from kernel heap memory, via vectors involving an SIOCGIWESSID ioctl call that specifies a large buffer size. La función cfg80211_wext_giwessid en net/wireless/wext-compat.c en el kernel de Linux anterior a v2.6.36-rc3-next-20100831 no inicializa adecuadamente determinadas estructuras de miembros, lo que permite a usuarios locales aprovechar un error off-by-one en la función net/wireless/wext-core.c y obtener información potencialmente sensible desde la memoria dinámica (heap) del kernel, a través de vectores que involucran una llamada SIOCGIWESSID ioctl que especifica un gran tamaño de búfer. • http://forums.grsecurity.net/viewtopic.php?f=3&t=2290 http://git.kernel.org/?p=linux/kernel/git/linville/wireless-2.6.git%3Ba=commit%3Bh=42da2f948d949efd0111309f5827bf0298bcc9a4 http://grsecurity.net/~spender/wireless-infoleak-fix2.patch http://lists.opensuse.org/opensuse-security-announce/2010-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-02/msg00000.html http://lkml.org/lkml/2010/8/27/413 http://lkml.org/lkml/2010/8/30/127 http://lkml.org/lkml • CWE-193: Off-by-one Error •
