CVSS: 6.2EPSS: 0%CPEs: 3EXPL: 0CVE-2015-3339 – kernel: race condition between chown() and execve()
https://notcve.org/view.php?id=CVE-2015-3339
Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel before 3.19.6 allows local users to gain privileges by executing a setuid program at a time instant when a chown to root is in progress, and the ownership is changed but the setuid bit is not yet stripped. Condición de carrera en la función prepare_binprm en fs/exec.c en el kernel de Linux anterior a 3.19.6 permite a usuarios locales ganar privilegios mediante la ejecución de un programa setuid en un instancia de tiempo que un chown a root está en progreso, y el propietario ha cambiado pero el bit setuid todavía no se ha eliminado. A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8b01fc86b9f425899f8a3a8fc1c47d73c2c20543 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/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00008.html http://l • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 9.3EPSS: 0%CPEs: 11EXPL: 0CVE-2015-3331 – Kernel: crypto: buffer overruns in RFC4106 implementation using AESNI
https://notcve.org/view.php?id=CVE-2015-3331
The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket. La función __driver_rfc4106_decrypt en arch/x86/crypto/aesni-intel_glue.c en el kernel de Linux anterior a 3.19.3 no determina correctamente las localizaciones de memoria utilizadas para datos cifrados, Lo que permite a atacantes dependientes de contexto causar una denegación de servicio (desbordamiento de buffer y caída de sistema) o posiblemente ejecutar código arbitrario mediante la provocación de una llamada de API Crypto, tal y como fue demostrado por el uso de un programa de pruebas de libkcapi con un socket AF_ALG(aead). A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ccfe8c3f7e52ae83155cb038753f4c75b774ca8a http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00011.html http://rhn.red • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.
