CVE-2015-4170 – kernel: pty layer race condition on tty ldisc shutdown.
https://notcve.org/view.php?id=CVE-2015-4170
Race condition in the ldsem_cmpxchg function in drivers/tty/tty_ldsem.c in the Linux kernel before 3.13-rc4-next-20131218 allows local users to cause a denial of service (ldsem_down_read and ldsem_down_write deadlock) by establishing a new tty thread during shutdown of a previous tty thread. Condición de carrera en la función ldsem_cmpxchg en drivers/tty/tty_ldsem.c en el kernel de Linux en versiones anteriores a 3.13-rc4-next-20131218 permite a usuarios locales provocar una denegación de servicio (interbloqueo de ldsem_down_read y ldsem_down_write) estableciendo un nuevo hilo tty durante la desconexión de un hilo tty previo. A flaw was discovered in the way the Linux kernel's TTY subsystem handled the tty shutdown phase. A local, unprivileged user could use this flaw to cause denial of service on the system by holding a reference to the ldisc lock during tty shutdown, causing a deadlock. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cf872776fc84128bb779ce2b83a37c884c3203ae http://www.openwall.com/lists/oss-security/2015/05/26/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/74820 https://access.redhat.com/errata/RHSA-2016:1395 https://bugzilla.redhat.com/show_bug.cgi?id=1218879 https://github.com/torvalds/linux/commit/cf872776fc84128bb779ce2b83a37c884c3203ae https://www.kernel.org/pub/linu • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-667: Improper Locking •
CVE-2015-8126 – libpng: Buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions
https://notcve.org/view.php?id=CVE-2015-8126
Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image. Múltiples desbordamientos de buffer en las funciones (1) png_set_PLTE y (2) png_get_PLTE en libpng en versiones anteriores a 1.0.64, 1.1.x y 1.2.x en versiones anteriores a 1.2.54, 1.3.x y 1.4.x en versiones anteriores a 1.4.17, 1.5.x en versiones anteriores a 1.5.24 y 1.6.x en versiones anteriores a 1.6.19 permiten a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente tener otro impacto no especificado a través de un valor bit-depth pequeño en un fragmento IHDR (también conocido como image header) en una imagen PNG. It was discovered that the png_get_PLTE() and png_set_PLTE() functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer overflow or out-of-bounds reads. An attacker could exploit this to cause a crash or potentially execute arbitrary code by tricking an unsuspecting user into processing a specially crafted PNG image. • http://googlechromereleases.blogspot.com/2016/03/stable-channel-update.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172324.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172620.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172647.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172663.html http://lists.fedoraproject.org/pipermail • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •
