CVSS: 7.5EPSS: 1%CPEs: 49EXPL: 0CVE-2013-7439 – libX11: buffer overflow in MakeBigReq macro
https://notcve.org/view.php?id=CVE-2013-7439
Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h in X11R6.x and libX11 before 1.6.0 allow remote attackers to have unspecified impact via a crafted request, which triggers a buffer overflow. Múltiples errores de superación de límite (off-by-one) en los macros (1) MakeBigReq y (2) SetReqLen en include/X11/Xlibint.h en X11R6.x y libX11 anterior a 1.6.0 permiten a atacantes remotos tener un impacto no especificado a través de una solicitud manipulada, lo que provoca un desbordamiento de buffer. • http://lists.x.org/archives/xorg-announce/2015-April/002561.html http://seclists.org/oss-sec/2015/q2/81 http://www.debian.org/security/2015/dsa-3224 http://www.oracle.com/technetwork/topics/security/bulletinjul2015-2511963.html http://www.securityfocus.com/bid/73962 http://www.ubuntu.com/usn/USN-2568-1 https://bugs.freedesktop.org/show_bug.cgi?id=56508 https://access.redhat.com/security/cve/CVE-2013-7439 https://bugzilla.redhat.com/show_bug.cgi?id=1209943 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-189: Numeric Errors •
CVSS: 6.5EPSS: 1%CPEs: 3EXPL: 0CVE-2014-8102 – xorg-x11-server: out of bounds access due to not validating length or offset values in XFixes extension
https://notcve.org/view.php?id=CVE-2014-8102
The SProcXFixesSelectSelectionInput function in the XFixes extension in X.Org X Window System (aka X11 or X) X11R6.8.0 and X.Org Server (aka xserver and xorg-server) before 1.16.3 allows remote authenticated users to cause a denial of service (out-of-bounds read or write) or possibly execute arbitrary code via a crafted length value. La función SProcXFixesSelectSelectionInput en la extensión XFixes en X.Org X Window System (también conocido como X11 o X) X11R6.8.0 y X.Org Server (también conocido como xserver y xorg-server) anterior a 1.16.3 permite a usuarios remotos autenticados causar una denegación de servicio (lectura o escritura fuera de rango) o posiblemente ejecutar código arbitrario a través de un valor de longitud manipulado. Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server. • http://advisories.mageia.org/MGASA-2014-0532.html http://secunia.com/advisories/61947 http://secunia.com/advisories/62292 http://www.debian.org/security/2014/dsa-3095 http://www.mandriva.com/security/advisories?name=MDVSA-2015:119 http://www.oracle.com/technetwork/topics/security/bulletinjan2015-2370101.html http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html http://www.securityfocus.com/bid/71608& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
