CVE-2018-5740 – A flaw in the "deny-answer-aliases" feature can cause an assertion failure in named
https://notcve.org/view.php?id=CVE-2018-5740
"deny-answer-aliases" is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. Affects BIND 9.7.0->9.8.8, 9.9.0->9.9.13, 9.10.0->9.10.8, 9.11.0->9.11.4, 9.12.0->9.12.2, 9.13.0->9.13.2. "deny-answer-aliases" es una característica poco utilizada que pretende ayudar a los operadores recursivos del servidor a proteger a los usuarios finales contra ataques de reenlace DNS, un método para poder eludir el modelo de seguridad empleado por los navegadores del cliente. Sin embargo, un defecto en esta característica hace que sea sencillo experimentar un fallo de aserción en name.c. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00027.html http://www.securityfocus.com/bid/105055 http://www.securitytracker.com/id/1041436 https://access.redhat.com/errata/RHSA-2018:2570 https://access.redhat.com/errata/RHSA-2018:2571 https://kb.isc.org/docs/aa-01639 https://lists.debian.org/debian-lts-announce/2018/08/msg00033.html https://lists.debian.org/debian-lts-announce/2021/11 • CWE-617: Reachable Assertion •
CVE-2018-15911 – ghostscript: Uninitialized memory access in the aesdecode operator (699665)
https://notcve.org/view.php?id=CVE-2018-15911
In Artifex Ghostscript 9.23 before 2018-08-24, attackers able to supply crafted PostScript could use uninitialized memory access in the aesdecode operator to crash the interpreter or potentially execute code. En Artifex Ghostscript 9.23 antes del 24/08/2018, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear un acceso a la memoria no inicializada en el operador aesdecode para provocar el cierre inesperado del intérprete o ejecutar código. It was discovered that ghostscript did not properly verify the key used in aesdecode. An attacker could possibly exploit this to bypass the -dSAFER protection and crash ghostscript or, possibly, execute arbitrary code in the ghostscript context via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=8e9ce5016db968b40e4ec255a3005f2786cce45f http://www.securityfocus.com/bid/105122 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699665 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44101 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://support.f5.com/csp/article/K22141757?utm_source=f5support&%3Butm_medium= • CWE-456: Missing Initialization of a Variable CWE-908: Use of Uninitialized Resource •
CVE-2018-15908 – ghostscript: .tempfile file permission issues (699657)
https://notcve.org/view.php?id=CVE-2018-15908
In Artifex Ghostscript 9.23 before 2018-08-23, attackers are able to supply malicious PostScript files to bypass .tempfile restrictions and write files. En Artifex Ghostscript 9.23 antes del 23/08/2018, los atacantes pueden proporcionar archivos PostScript maliciosos para omitir las restricciones .tempfile y escribir en archivos. It was discovered that the ghostscript .tempfile function did not properly handle file permissions. An attacker could possibly exploit this to exploit this to bypass the -dSAFER protection and delete files or disclose their content via a specially crafted PostScript document. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=0d3901189f245232f0161addf215d7268c4d05a3 https://access.redhat.com/errata/RHSA-2018:3650 https://lists.debian.org/debian-lts-announce/2018/09/msg00015.html https://security.gentoo.org/glsa/201811-12 https://usn.ubuntu.com/3768-1 https://www.debian.org/security/2018/dsa-4288 https://www.kb.cert.org/vuls/id/332928 https://access.redhat.com/security/cve/CVE-2018-15908 https://bugzilla.redhat.com/show_bug.cgi?id=1619756 •
CVE-2018-15910 – ghostscript: LockDistillerParams type confusion (699656)
https://notcve.org/view.php?id=CVE-2018-15910
In Artifex Ghostscript before 9.24, attackers able to supply crafted PostScript files could use a type confusion in the LockDistillerParams parameter to crash the interpreter or execute code. En Artifex Ghostscript en versiones anteriores a la 9.24, los atacantes que puedan proporcionar archivos PostScript manipulados podrían emplear una confusión de tipos en el parámetro LockDistillerParams para provocar el cierre inesperado del intérprete o ejecutar código.
