CVE-2014-9585 – kernel: ASLR bruteforce possible for vdso library
https://notcve.org/view.php?id=CVE-2014-9585
The vdso_addr function in arch/x86/vdso/vma.c in the Linux kernel through 3.18.2 does not properly choose memory locations for the vDSO area, which makes it easier for local users to bypass the ASLR protection mechanism by guessing a location at the end of a PMD. La función vdso_addr en arch/x86/vdso/vma.c en el kernel de Linux hasta 3.18.2 no elige correctamente localizaciones de memoria para la área vDSO, lo que facilita a usuarios locales evadir el mecanismo de protección ASLR mediante la adivinación de una localización al final de un PMD. An information leak flaw was found in the way the Linux kernel's Virtual Dynamic Shared Object (vDSO) implementation performed address randomization. A local, unprivileged user could use this flaw to leak kernel memory addresses to user-space. • http://git.kernel.org/?p=linux/kernel/git/luto/linux.git%3Ba=commit%3Bh=bc3b94c31d65e761ddfe150d02932c65971b74e2 http://git.kernel.org/?p=linux/kernel/git/tip/tip.git%3Ba=commit%3Bh=fbe1bf140671619508dfa575d74a185ae53c5dbb http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148480.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg0 •
CVE-2014-9529 – kernel: use-after-free during key garbage collection
https://notcve.org/view.php?id=CVE-2014-9529
Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. Condición de carrera en la función key_gc_unused_keys en security/keys/gc.c en el kernel de Linux hasta 3.18.2 permite a usuarios locales causar una denegación de servicio (corrupción de memoria o pánico) o posiblemente tener otro impacto no especificado a través de comandos keyctl que provocan el acceso a un miembro de la estructura clave durante la recogida de basura de una clave. A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a3a8784454692dd72e5d5d34dcdab17b4420e74c http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147864.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/147973.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat.com/errata/RHSA-2015-1137.html http://rhn.redhat.com/errata/RHSA-2015-1138& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2014-8139 – unzip: CRC32 verification heap-based buffer overread (oCERT-2014-011)
https://notcve.org/view.php?id=CVE-2014-8139
Heap-based buffer overflow in the CRC32 verification in Info-ZIP UnZip 6.0 and earlier allows remote attackers to execute arbitrary code via a crafted zip file in the -t command argument to the unzip command. Un desbordamiento del búfer en la región heap de la memoria en la comprobación de CRC32 en Info-ZIP UnZip versiones 6.0 y anteriores, permite a atacantes remotos ejecutar código arbitrario por medio de un archivo zip diseñado en el argumento del comando -t para el comando unzip. A buffer overflow flaw was found in the way unzip computed the CRC32 checksum of certain extra fields of a file. A specially crafted Zip archive could cause unzip to crash when the archive was tested with unzip's '-t' option. • http://www.ocert.org/advisories/ocert-2014-011.html http://www.securitytracker.com/id/1031433 https://access.redhat.com/errata/RHSA-2015:0700 https://bugzilla.redhat.com/show_bug.cgi?id=1174844 https://access.redhat.com/security/cve/CVE-2014-8139 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
