CVE-2012-0044 – kernel: drm: integer overflow in drm_mode_dirtyfb_ioctl()
https://notcve.org/view.php?id=CVE-2012-0044
Integer overflow in the drm_mode_dirtyfb_ioctl function in drivers/gpu/drm/drm_crtc.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 3.1.5 allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted ioctl call. Un desbordamiento de entero en la función de drm_mode_dirtyfb_ioctl en drivers/gpu/drm/ drm_crtc.c en el subsistema "Direct Rendering Manager" (DRM) en el kernel de Linux en versiones anteriores a la v3.1.5 permite a usuarios locales obtener privilegios o causar una denegación de servicio (por corrupción de memoria) a través de una llamada a ioctl debdamente modificada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a5cd335165e31db9dbab636fd29895d41da55dd2 http://rhn.redhat.com/errata/RHSA-2012-0743.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.1.5 http://www.openwall.com/lists/oss-security/2012/01/12/1 http://www.securityfocus.com/bid/51371 http://www.ubuntu.com/usn/USN-1555-1 http://www.ubuntu.com/usn/USN-1556-1 https://bugzilla.redhat.com/show_bug.cgi?id=772894 https:/& • CWE-190: Integer Overflow or Wraparound •
CVE-2012-0056 – Linux Kernel 2.6.39 < 3.2.2 (x86/x64) - 'Mempodipper' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2012-0056
The mem_write function in the Linux kernel before 3.2.2, when ASLR is disabled, does not properly check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by modifying process memory, as demonstrated by Mempodipper. La función mem_write en el kernel de Linux anterior a versión 3.2.2, cuando ASLR está deshabilitado, no comprueba apropiadamente los permisos al escribir en /proc/(pid)/mem, lo que permite a los usuarios locales alcanzar privilegios al modificar la memoria del proceso, como es demostrado por Mempodipper . • https://www.exploit-db.com/exploits/35161 https://www.exploit-db.com/exploits/18411 https://github.com/pythonone/CVE-2012-0056 https://github.com/srclib/CVE-2012-0056 http://blog.zx2c4.com/749 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=e268337dfe26dfc7efd422a804dbb27977a3cccc http://secunia.com/advisories/47708 http://ubuntu.com/usn/usn-1336-1 http://www.kb.cert.org/vuls/id/470151 http://www.kernel.org/pub/linux/kernel/ • CWE-264: Permissions, Privileges, and Access Controls CWE-863: Incorrect Authorization •
CVE-2012-0207 – Linux Kernel 2.6.36 IGMP - Remote Denial of Service
https://notcve.org/view.php?id=CVE-2012-0207
The igmp_heard_query function in net/ipv4/igmp.c in the Linux kernel before 3.2.1 allows remote attackers to cause a denial of service (divide-by-zero error and panic) via IGMP packets. La función de igmp_heard_query net/ipv4/igmp.c en el kernel de Linux en versiones anteriores a la v3.2.1 permite a atacantes remotos causar una denegación de servicio (error de división por cero y el "kernel panic") a través de paquetes IGMP. • https://www.exploit-db.com/exploits/18378 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654876 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a8c1f65c79cbbb2f7da782d4c9d15639a9b94b27 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.1 http://www.openwall.com/lists/oss-security/2012/01/10/5 https://bugzilla.redhat.com/show_bug.cgi?id=772867 https://github.com/torvalds/linux/commit/25c413ad0029ea86008234be28aee33456e53e5b https://github.com& • CWE-369: Divide By Zero •
CVE-2011-4127 – kernel: possible privilege escalation via SG_IO ioctl
https://notcve.org/view.php?id=CVE-2011-4127
The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume. El kernel de Linux anterior a v3.2.2 no restringe adecuadamente llamadas SG_IO ioctl, permitiendo a usuarios locales eludir restricciones de lectura y escritura en disco mediante el envío de un comando SCSI a (1) un dispositivo de bloques de particiones o (2) un volumen LVM. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=0bfc96cb77224736dfa35c3c555d37b3646ef35e http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ec8013beddd717d1740cfefb1a9b900deef85462 http://lists.opensuse.org/opensuse-security-announce/2012-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://secunia.com/advisories/48898 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.2 http://www& • CWE-264: Permissions, Privileges, and Access Controls CWE-284: Improper Access Control •
CVE-2011-4077 – kernel: xfs: potential buffer overflow in xfs_readlink()
https://notcve.org/view.php?id=CVE-2011-4077
Buffer overflow in the xfs_readlink function in fs/xfs/xfs_vnodeops.c in XFS in the Linux kernel 2.6, when CONFIG_XFS_DEBUG is disabled, allows local users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via an XFS image containing a symbolic link with a long pathname. Un desbordamiento de búfer en la función xfs_readlink en fs/xfs/xfs_vnodeops.c en XFS en el kernel de Linux v2.6, cuando CONFIG_XFS_DEBUG está desactivado, permite a usuarios locales provocar una denegación de servicio (corrupción de memoria y caída del sistema) y posiblemente ejecutar código de su elección a través de una imagen XFS que contiene un enlace simbólico con una ruta demasiado larga. • http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://oss.sgi.com/archives/xfs/2011-10/msg00345.html http://secunia.com/advisories/48964 http://www.openwall.com/lists/oss-security/2011/10/26/1 http://www.openwall.com/lists/oss-security/2011/10/26/3 http://xorl.wordpress.com/2011/12/07/cve-2011-4077-linux-kernel-xfs-readlink-memory-corruption https://bugzilla.redhat.com/show_bug.cgi?id=749156 https://access.redhat.com/security/cve/CVE-2011-4077 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
