CVSS: 5.4EPSS: 0%CPEs: 7EXPL: 1CVE-2014-3144 – Kernel: filter: prevent nla extensions to peek beyond the end of the message
https://notcve.org/view.php?id=CVE-2014-3144
The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced. Las implementaciones de extensión (1) BPF_S_ANC_NLATTR y (2) BPF_S_ANC_NLATTR_NEST en la función sk_run_filter en net/core/filter.c en el kernel de Linux hasta 3.14.3 no comprueban si un valor de cierta longitud es lo suficientemente grande, lo que permite a usuarios locales causar una denegación de servicio (subdesbordamiento de enteros y caída de sistema) a través de instrucciones BPF manipuladas. NOTA: el código afectado fue trasladado a las funciones __skb_get_nlattr y __skb_get_nlattr_nest antes de anunciar la vulnerabilidad. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=05ab8f2647e4221cbdb3856dd7d32bd5407316b3 http://linux.oracle.com/errata/ELSA-2014-3052.html http://secunia.com/advisories/58990 http://secunia.com/advisories/59311 http://secunia.com/advisories/59597 http://secunia.com/advisories/60613 http://www.debian.org/security/2014/dsa-2949 http://www.openwall.com/lists/oss-security/2014/05/09/6 http://www.securityfocus.com/bid/67309 http://www.ubuntu. • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2014-3145
The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced. La implementación de extensión BPF_S_ANC_NLATTR_NEST en la función sk_run_filter en net/core/filter.c en el kernel de Linux hasta 3.14.3 utiliza el orden inverso en cierta resta, lo que permite a usuarios locales causar una denegación de servicio (sobrelectura y caída de sistema) a través de instrucciones BPF manipuladas. NOTA: el código afectado fue trasladado a la función __skb_get_nlattr_nest antes de anunciar la vulnerabilidad. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=05ab8f2647e4221cbdb3856dd7d32bd5407316b3 http://linux.oracle.com/errata/ELSA-2014-3052.html http://secunia.com/advisories/58990 http://secunia.com/advisories/59311 http://secunia.com/advisories/59597 http://secunia.com/advisories/60613 http://www.debian.org/security/2014/dsa-2949 http://www.openwall.com/lists/oss-security/2014/05/09/6 http://www.securityfocus.com/bid/67321 http://www.securitytra • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2014-2706
Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c. Condición de carrera en el subsistema mac80211 en el kernel de Linux anterior a 3.13.7 permite a atacantes remotos causar una denegación de servicio (caída de sistema) a través de trafico de red que no interactúa debidamente con el estado WLAN_STA_PS_STA (también conocido como el modo power-save), relacionado con sta_info.c y tx.c. A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=1d147bfa64293b2723c4fec50922168658e613ba http://linux.oracle.com/errata/ELSA-2014-3052.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://secunia.com/advisories/60613 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.7 http://www.openwall.com/lists/oss-security/2014/04/01/8 http:/&# • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The monlist feature in ntp_request.c in ntpd in NTP before 4.2.7p26 allows remote attackers to cause a denial of service (traffic amplification) via forged (1) REQ_MON_GETLIST or (2) REQ_MON_GETLIST_1 requests, as exploited in the wild in December 2013.
