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 •

The tcp_check_send_head function in include/net/tcp.h in the Linux kernel before 4.7.5 does not properly maintain certain SACK state after a failed data copy, which allows local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option. La función tcp_check_send_head en include/net/tcp.h en el kernel de Linux en versiones anteriores a 4.7.5 no mantiene adecuadamente cierto estado SACK tras una copia de datos fallida, lo que permite a usuarios locales provocar una denegación de servicio (uso después de liberación de memoria tcp_xmit_retransmit_queue y caída de sistema ) a través de una opción SACK manipulada. A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection. • https://www.exploit-db.com/exploits/40731 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bb1fceca22492109be12640d49f5ea5a544c6bb4 http://rhn.redhat.com/errata/RHSA-2017-0036.html http://rhn.redhat.com/errata/RHSA-2017-0086.html http://rhn.redhat.com/errata/RHSA-2017-0091.html http://rhn.redhat.com/errata/RHSA-2017-0113.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.5 http://www.openwall.com/lists/oss-security/2016/08/15/ • CWE-416: Use After Free •
