CVE-2014-0069 – kernel: cifs: incorrect handling of bogus user pointers during uncached writes
https://notcve.org/view.php?id=CVE-2014-0069
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente operaciones de escritura no en caché que copian menos bytes de los solicitados, lo que permite a usuarios locales obtener información sensible de la memoria del kernel, causar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente ganar privilegios a través de una llamada al sistema writev con un puntero manipulado. • http://article.gmane.org/gmane.linux.kernel.cifs/9401 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d81de8e8667da7135d3a32a964087c0faf5483f http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00026.html http://rhn.redhat.com/errata/RHSA-2014-0328.html http://www.openwall.com/lists/oss-security/2014/02/17/4 http://www.securityfocus.com/bid/65588 https://bugzilla.redhat.com/show_bug.cgi?id=1064253 https://github.com/torvalds/linux/comm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2014-2039 – Kernel: s390: crash due to linkage stack instructions
https://notcve.org/view.php?id=CVE-2014-2039
arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction. arch/s390/kernel/head64.S en el kernel de Linux anterior a 3.13.5 en la plataforma s390 no maneja debidamente intentos de uso de la pila de vinculación, lo que permite a usuarios locales causar una denegación de servicio (caída de sistema) mediante la ejecución de una instrucción manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8d7f6690cedb83456edd41c9bd583783f0703bf0 http://linux.oracle.com/errata/ELSA-2014-0771.html http://secunia.com/advisories/59262 http://secunia.com/advisories/59309 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.5 http://www.openwall.com/lists/oss-security/2014/02/20/14 http://www.securityfocus.com/bid/65700 https://bugzilla.redhat.com/show_bug.cgi?id=1067558 https://github.com • CWE-20: Improper Input Validation •
CVE-2014-1690 – Kernel: netfilter: nf_nat: leakage of uninitialized buffer in IRC NAT helper
https://notcve.org/view.php?id=CVE-2014-1690
The help function in net/netfilter/nf_nat_irc.c in the Linux kernel before 3.12.8 allows remote attackers to obtain sensitive information from kernel memory by establishing an IRC DCC session in which incorrect packet data is transmitted during use of the NAT mangle feature. La función de ayuda en net/netfilter/nf_nat_irc.c en el kernel de Linux anterior a 3.12.8 permite a atacantes remotos obtener información sensible de la memoria del kernel mediante el establecimiento de una sesión IRC DCC en la cual datos de paquetes incorrectos son transmitidos durante el uso de la funcionalidad NAT mangle. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2690d97ade05c5325cbf7c72b94b90d265659886 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.12.8 http://www.openwall.com/lists/oss-security/2014/01/28/3 http://www.ubuntu.com/usn/USN-2137-1 http://www.ubuntu.com/usn/USN-2140-1 http://www.ubuntu.com/usn/USN-2158-1 https://bugzilla.redhat.com/show_bug.cgi?id=1058748 https://github.com/torvalds/linux/commit/2690d97ade05c5325cbf7c72b94 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2012-6638 – Kernel: net: tcp: potential DoS via SYN+FIN messages
https://notcve.org/view.php?id=CVE-2012-6638
The tcp_rcv_state_process function in net/ipv4/tcp_input.c in the Linux kernel before 3.2.24 allows remote attackers to cause a denial of service (kernel resource consumption) via a flood of SYN+FIN TCP packets, a different vulnerability than CVE-2012-2663. La función tcp_rcv_state_process en net/ipv4/tcp_input.c en el kernel de Linux anterior a 3.2.24 permite a atacantes remotos causar una denegación de servicio (consumo de recursos del kernel) a través de una inundación de paquetes TCP SYN+FIN, una vulnerabilidad diferente a CVE-2012-2663. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=fdf5af0daf8019cec2396cdef8fb042d80fe71fa http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.24 https://bugzilla.redhat.com/show_bug.cgi?id=826702 https://github.com/torvalds/linux/commit/fdf5af0daf8019cec2396cdef8fb042d80fe71fa https://access.redhat.com/security/cve/CVE-2012-6638 https://bugzilla.redhat.com/show_bug.cgi?id=1066055 • CWE-400: Uncontrolled Resource Consumption •
