CVSS: 6.2EPSS: 0%CPEs: 1EXPL: 0CVE-2016-7042 – kernel: Stack corruption while reading /proc/keys when gcc stack protector is enabled
https://notcve.org/view.php?id=CVE-2016-7042
The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file. La función proc_keys_show en security/keys/proc.c en el kernel de Linux hasta la versión 4.8.2, cuando el protector de pila GNU Compiler Collection (gcc) está habilitado, utiliza un tamaño de búfer incorrecto para ciertos datos de tiempo de espera, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de la memoria de pila y pánico) leyendo el archivo /proc/keys. It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks. • http://rhn.redhat.com/errata/RHSA-2017-0817.html http://www.openwall.com/lists/oss-security/2016/10/13/5 http://www.securityfocus.com/bid/93544 https://access.redhat.com/errata/RHSA-2017:1842 https://access.redhat.com/errata/RHSA-2017:2077 https://access.redhat.com/errata/RHSA-2017:2669 https://bugzilla.redhat.com/show_bug.cgi?id=1373966 https://source.android.com/security/bulletin/2017-01-01.html https://access.redhat.com/security/cve/CVE-2016-7042 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba. La funcionalidad mbcache en las implementaciones del sistema de archivos ext2 y ext4 en el kernel de Linux en versiones anteriores a 4.6 no maneja adecuadamente bloque de almacenamiento en caché xattr, lo que permite a usuarios locales provocar una denegación de servicio (bloqueo débil) a través de operaciones de sistema de archivos en entornos que usan muchos atributos, como se demuestra por Ceph y Samba. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=82939d7999dfc1f1998c4b1c12e2f19edbdff272 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be0726d33cb8f411945884664924bed3cb8c70ee http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f9a61eb4e2471c56a63cd804c7474128138c38ac http://www.openwall.com/lists/oss-security/2016/08/22/2 http://www.openwall.com/lists/oss-security/2016/08/25/4 https://bugzilla.kernel.org/show_bug.cgi?id=10 • CWE-19: Data Processing Errors •
