CVE-2016-7943
https://notcve.org/view.php?id=CVE-2016-7943
The XListFonts function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges via vectors involving length fields, which trigger out-of-bounds write operations. La función XListFonts en X.org libX11 en versiones anteriores a 1.6.4 podría permitir a servidores remotos X obtener privilegios a través de vectores que involucran campos de longitud, que desencadena operaciones de escritura fuera de límites. • http://www.openwall.com/lists/oss-security/2016/10/04/2 http://www.openwall.com/lists/oss-security/2016/10/04/4 http://www.securityfocus.com/bid/93362 http://www.securitytracker.com/id/1036945 https://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=8c29f1607a31dac0911e45a0dd3d74173822b3c9 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMCVDXMFPXR7QGMKDG22WPPJCXH2X3L7 https://lists.x.org/archives/xorg-announce/2016-October/002720.html https://security.g • CWE-787: Out-of-bounds Write •

The XGetImage function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges via vectors involving image type and geometry, which triggers out-of-bounds read operations. La función XGetImage en X.org libX11 en versiones anteriores a 1.6.4 podría permitir a servidores remotos X obtener privilegios a través de vectores que involucran tipo de imagen y geometría, que desencadena operaciones de lectura fuera de límites. • http://www.openwall.com/lists/oss-security/2016/10/04/2 http://www.openwall.com/lists/oss-security/2016/10/04/4 http://www.securityfocus.com/bid/93363 http://www.securitytracker.com/id/1036945 https://cgit.freedesktop.org/xorg/lib/libX11/commit/?id=8ea762f94f4c942d898fdeb590a1630c83235c17 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMCVDXMFPXR7QGMKDG22WPPJCXH2X3L7 https://lists.x.org/archives/xorg-announce/2016-October/002720.html https://security.g • CWE-264: Permissions, Privileges, and Access Controls CWE-787: Out-of-bounds Write •
CVE-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 •
CVE-2013-2004 – libX11: unbounded recursion leading to stack-overflow
https://notcve.org/view.php?id=CVE-2013-2004
The (1) GetDatabase and (2) _XimParseStringFile functions in X.org libX11 1.5.99.901 (1.6 RC1) and earlier do not restrict the recursion depth when processing directives to include files, which allows X servers to cause a denial of service (stack consumption) via a crafted file. Las funciones (1) GetDatabase y (2) _XimParseStringFile en X.org libX11 v1.5.99.901 (1.6 RC1) y anteriores no limitan la profundidad de recursividad en el tratamiento de las directivas de inclusión de archivos, lo que permite causar una denegación de servicio a los servidores X (por consumo de pila) a través de un archivo diseñado para tal fin. Two stack-based buffer overflow flaws were found in the way libX11, the Core X11 protocol client library, processed certain user-specified files. A malicious X11 server could possibly use this flaw to crash an X11 client via a specially crafted file. • http://www.debian.org/security/2013/dsa-2693 http://www.openwall.com/lists/oss-security/2013/05/23/3 http://www.ubuntu.com/usn/USN-1854-1 http://www.x.org/wiki/Development/Security/Advisory-2013-05-23 https://access.redhat.com/security/cve/CVE-2013-2004 https://bugzilla.redhat.com/show_bug.cgi?id=959112 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
CVE-2013-1981 – libX11: Multiple integer overflows leading to heap-based buffer-overflows
https://notcve.org/view.php?id=CVE-2013-1981
Multiple integer overflows in X.org libX11 1.5.99.901 (1.6 RC1) and earlier allow X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to the (1) XQueryFont, (2) _XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5) XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8) XGetKeyboardMapping, (9) XGetWindowProperty, (10) XGetImage, (11) LoadColornameDB, (12) XrmGetFileDatabase, (13) _XimParseStringFile, or (14) TransFileName functions. Múltiples desbordamientos de enteros en X.org libX11 v1.5.99.901 (1.6 RC1) y anteriores permiten que los servidores X provoquen una asignación de memoria insuficiente y un desbordamiento de búfer a través de vectores relacionados con las funciones (1) XQueryFont, (2) _XF86BigfontQueryFont, (3) XListFontsWithInfo, (4) XGetMotionEvents, (5) XListHosts, (6) XGetModifierMapping, (7) XGetPointerMapping, (8) XGetKeyboardMapping, (9) XGetWindowProperty, y (10) XGetImage. • http://lists.fedoraproject.org/pipermail/package-announce/2013-May/106781.html http://www.debian.org/security/2013/dsa-2693 http://www.openwall.com/lists/oss-security/2013/05/23/3 http://www.securityfocus.com/bid/60120 http://www.ubuntu.com/usn/USN-1854-1 http://www.x.org/wiki/Development/Security/Advisory-2013-05-23 https://access.redhat.com/security/cve/CVE-2013-1981 https://bugzilla.redhat.com/show_bug.cgi?id=959040 • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •
