CVE-2015-1573 – kernel: panic while flushing nftables rules that reference deleted chains.
https://notcve.org/view.php?id=CVE-2015-1573
The nft_flush_table function in net/netfilter/nf_tables_api.c in the Linux kernel before 3.18.5 mishandles the interaction between cross-chain jumps and ruleset flushes, which allows local users to cause a denial of service (panic) by leveraging the CAP_NET_ADMIN capability. La función nft_flush_table en net/netfilter/nf_tables_api.c en el kernel de Linux en versiones anteriores a 3.18.5 no maneja adecuadamente la interacción entre saltos cross-chain y borrado de conjuntos de reglas, lo que permite a usuarios locales provocar una denegación de servicio (pánico) aprovechando la capacidad CAP_NET_ADMIN. A flaw was found in the way the nft_flush_table() function of the Linux kernel's netfilter tables implementation flushed rules that were referencing deleted chains. A local user who has the CAP_NET_ADMIN capability could use this flaw to crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a2f18db0c68fec96631c10cad9384c196e9008ac http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.18.5 http://www.openwall.com/lists/oss-security/2015/02/10/13 http://www.securityfocus.com/bid/72552 https://bugzilla.redhat.com/show_bug.cgi?id=1190966 https://github.com/torvalds/linux/commit/a2f18db0c68fec9 • CWE-19: Data Processing Errors CWE-416: Use After Free •
CVE-2015-1328 – Linux Kernel (Ubuntu / Fedora / RedHat) - 'Overlayfs' Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2015-1328
The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace. La implementación de overlayfs en el paquete linux (también conocido como kernel Linux) en versiones anteriores a 3.19.0-21.21 en Ubuntu hasta la versión 15.04 no comprueba adecuadamente permisos para la creación de archivos en el directorio de sistema de archivos upper, lo que permite a usuarios locales obtener acceso de root aprovechando una configuración donde overlayfs es permitido en un espacio de nombre de montaje arbitrario. • https://www.exploit-db.com/exploits/40688 https://www.exploit-db.com/exploits/37293 https://www.exploit-db.com/exploits/37292 https://github.com/elit3pwner/CVE-2015-1328-GoldenEye https://github.com/notlikethis/CVE-2015-1328 https://github.com/SR7-HACKING/LINUX-VULNERABILITY-CVE-2015-1328 http://seclists.org/oss-sec/2015/q2/717 http://www.exploit-db.com/exploits/40688 http://www.securityfocus.com/bid/75206 https://people.canonical.com/~ubuntu-security/cve/2015/CVE • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2015-4167
https://notcve.org/view.php?id=CVE-2015-4167
The udf_read_inode function in fs/udf/inode.c in the Linux kernel before 3.19.1 does not validate certain length values, which allows local users to cause a denial of service (incorrect data representation or integer overflow, and OOPS) via a crafted UDF filesystem. Vulnerabilidad en la función udf_read_inode en fs/udf/inode.c en el kernel de Linux en versiones anteriores a 3.19.1, no valida determinados valores de longitud, lo que permite a usuarios locales provocar una denegación de servicio (representación de datos incorrecta o desbordamiento de enteros y OOPS) a través de un sistema de archivos UDF manipulado. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=23b133bdc452aa441fcb9b82cbf6dd05cfd342d0 http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00021.html http://www.debian.org/security/2015/dsa-3290 http://www.debian.org/security/2015/dsa-3313 • CWE-189: Numeric Errors •
CVE-2015-3636 – kernel: ping sockets: use-after-free leading to local privilege escalation
https://notcve.org/view.php?id=CVE-2015-3636
The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect. Vulnerabilidad en la función ping_unhash en net/ipv4/ping.c en el kernel de Linux en versiones anteriores a 4.0.3, no inicializa una cierta estructura de datos de lista durante una operación unhash, lo que permite a usuarios locales obtener privilegios o causar una denegación de servicio (uso después de liberación de memoria y caída del sistema) mediante el aprovechamiento de la capacidad de hacer una llamada a un socket de sistema SOCK_DGRAM para el protocolo IPROTO_ICMP o IPROTO_ICMPV6 y entonces hacer una llamada al sistema de conexión tras una desconexión. It was found that the Linux kernel's ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system. • https://github.com/fi01/CVE-2015-3636 https://github.com/a7vinx/CVE-2015-3636 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a134f083e79fb4c3d0a925691e732c56911b4326 http://lists.fedoraproject.org/pipermail/package-announce/2015-May/157788.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/157897.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158804.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http • CWE-416: Use After Free •
CVE-2015-0275 – kernel: fs: ext4: fallocate zero range page size > block size BUG()
https://notcve.org/view.php?id=CVE-2015-0275
