CVE-2018-12359 – Mozilla: Buffer overflow using computed size of canvas element
https://notcve.org/view.php?id=CVE-2018-12359
A buffer overflow can occur when rendering canvas content while adjusting the height and width of the canvas element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61. Puede ocurrir un desbordamiento de búfer al renderizar contenido canvas al ajustar dinámicamente la altura y anchura del elemento canvas, lo que provoca que los datos se escriban fuera de los límites calculados actualmente. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/104555 http://www.securitytracker.com/id/1041193 https://access.redhat.com/errata/RHSA-2018:2112 https://access.redhat.com/errata/RHSA-2018:2113 https://access.redhat.com/errata/RHSA-2018:2251 https://access.redhat.com/errata/RHSA-2018:2252 https://bugzilla.mozilla.org/show_bug.cgi?id=1459162 https://lists.debian.org/debian-lts-announce/2018/06/msg00014.html https://lists.debian.org/debian-lts-announce/2018/07/msg00013.html https://securi • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2018-10850 – 389-ds-base: race condition on reference counter leads to DoS using persistent search
https://notcve.org/view.php?id=CVE-2018-10850
389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service. 389-ds-base en versiones anteriores a la 1.4.0.10 y 1.3.8.3 es vulnerable a una condición de carrera por la forma en la que 389-ds-base gestiona las búsquedas persistentes. Esto resulta en un cierre inesperado si el servidor está bajo carga. Un atacante anónimo podría explotar este error para provocar una denegación de servicio (DoS). A race condition was found in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00033.html https://access.redhat.com/errata/RHSA-2018:2757 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10850 https://lists.debian.org/debian-lts-announce/2018/07/msg00018.html https://pagure.io/389-ds-base/c/8f04487f99a https://pagure.io/389-ds-base/issue/49768 https://access.redhat.com/security/cve/CVE-2018-10850 https://bugzilla.redhat.com/show_bug.cgi?id=1588056 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-12020 – gnupg2: Improper sanitization of filenames allows for the display of fake status messages and the bypass of signature verification
https://notcve.org/view.php?id=CVE-2018-12020
mainproc.c in GnuPG before 2.2.8 mishandles the original filename during decryption and verification actions, which allows remote attackers to spoof the output that GnuPG sends on file descriptor 2 to other programs that use the "--status-fd 2" option. For example, the OpenPGP data might represent an original filename that contains line feed characters in conjunction with GOODSIG or VALIDSIG status codes. mainproc.c en GnuPG en versiones anteriores a la 2.2.8 gestiona de manera incorrecta el nombre de archivo original durante las acciones de descifrado y verificación, lo que permite que atacantes remotos suplanten la salida que GnuPG envía en el descriptor de archivo 2 a otros programas que emplean la opción "--status-fd 2". Por ejemplo, los datos OpenPGP podrían representar un nombre de archivo original que contiene caracteres de nueva línea junto con los códigos de estado GOODSIG o VALIDSIG. A data validation flaw was found in the way gnupg processes file names during decryption and signature validation. An attacker may be able to inject messages into gnupg verbose message logging which may have the potential to bypass the integrity of signature authentication mechanisms and could have other unintended consequences if applications take action(s) based on parsed verbose gnupg output. • http://openwall.com/lists/oss-security/2018/06/08/2 http://packetstormsecurity.com/files/152703/Johnny-You-Are-Fired.html http://seclists.org/fulldisclosure/2019/Apr/38 http://www.openwall.com/lists/oss-security/2019/04/30/4 http://www.securityfocus.com/bid/104450 http://www.securitytracker.com/id/1041051 https://access.redhat.com/errata/RHSA-2018:2180 https://access.redhat.com/errata/RHSA-2018:2181 https://dev.gnupg.org/T4012 https://github.com/RUB-NDS/Johnny • CWE-20: Improper Input Validation CWE-706: Use of Incorrectly-Resolved Name or Reference •
CVE-2018-11806 – Qemu Slirp Networking Heap-based Buffer Overflow Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2018-11806
m_cat in slirp/mbuf.c in Qemu has a heap-based buffer overflow via incoming fragmented datagrams. m_cat en slirp/mbuf.c en Qemu tiene un desbordamiento de búfer basado en memoria dinámica (heap) mediante los datagramas entrantes fragmentados. A heap buffer overflow issue was found in the way SLiRP networking back-end in QEMU processes fragmented packets. It could occur while reassembling the fragmented datagrams of an incoming packet. A privileged user/process inside guest could use this flaw to crash the QEMU process resulting in DoS or potentially leverage it to execute arbitrary code on the host with privileges of the QEMU process. This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Qemu. • http://www.openwall.com/lists/oss-security/2018/06/07/1 http://www.securityfocus.com/bid/104400 https://access.redhat.com/errata/RHSA-2018:2462 https://access.redhat.com/errata/RHSA-2018:2762 https://access.redhat.com/errata/RHSA-2018:2822 https://access.redhat.com/errata/RHSA-2018:2887 https://access.redhat.com/errata/RHSA-2019:2892 https://bugzilla.redhat.com/show_bug.cgi?id=1586245 https://lists.debian.org/debian-lts-announce/2019/05/msg00010.html https://li • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
