CVE-2019-7317 – libpng: use-after-free in png_image_free in png.c
https://notcve.org/view.php?id=CVE-2019-7317
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute. La función png_image_free en el archivo png.c en libpng versiones 1.6.x anteriores a 1.6.37, presenta un uso de la memoria previamente liberada porque la función png_image_free_function es llamada bajo png_safe_execute. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00084.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00044.html http://packetstormsecurity.com/files/152561/Slackware-Security-Advisory-libpng-Updates.html http://www.securityfocus.com/bid/108098 https:/ • CWE-400: Uncontrolled Resource Consumption CWE-416: Use After Free •
CVE-2019-7310 – poppler: heap-based buffer over-read in XRef::getEntry in XRef.cc
https://notcve.org/view.php?id=CVE-2019-7310
In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. En la versión 0.73.0 de Poppler, una sobrelectura de búfer (debido a un error en la propiedad signedness de un número entero en la función XRef::getEntry function en XRef.cc) basada en memoria dinámica (heap) permite a los atacantes remotos causar una denegación de servicio (cierre inesperado de la aplicación) o, potencialmente, otro impacto no especificado mediante un documento PDF manipulado, tal y como queda demostrado con pdftocairo. • http://www.securityfocus.com/bid/106829 https://access.redhat.com/errata/RHSA-2019:2022 https://access.redhat.com/errata/RHSA-2019:2713 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12797 https://gitlab.freedesktop.org/poppler/poppler/issues/717 https://lists.debian.org/debian-lts-announce/2019/03/msg00008.html https://lists.debian.org/debian-lts-announce/2020/11/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BI7NLDN2 • CWE-125: Out-of-bounds Read CWE-681: Incorrect Conversion between Numeric Types •
CVE-2018-18506 – Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied
https://notcve.org/view.php?id=CVE-2018-18506
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65. Cuando la autodetección del proxy está habilitada, si un servidor web proporciona un archivo de autoconfiguración de proxy (PAC) o si dicho archivo se carga localmente, este último puede especificar peticiones al host local que están destinadas a enviarse a través del proxy hacia otro servidor. Este comportamiento está prohibido por defecto cuando un proxy se configura manualmente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00043.html http://www.securityfocus.com/bid/106773 https://access.redhat.com/errata/RHSA-2019:0622 https://access.redhat.com/errata/RHSA-2019:0623 https://access.redhat.com/errata/RHSA-2019:0680 https:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
