CVE-2018-18521 – elfutils: Divide-by-zero in arlib_add_symbols function in arlib.c
https://notcve.org/view.php?id=CVE-2018-18521
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled. Vulnerabilidades de división entre cero en la función arlib_add_symbols() en arlib.c en elfutils 0.174 permiten que los atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) con un archivo ELF manipulado, tal y como queda demostrado con eu-ranlib. Esto se debe a que se gestiona de manera incorrecta un sh_entsize con valor cero. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=23786 https://sourceware.org/ml/elfutils-devel/2018-q4/msg00055.html https://usn.ubuntu.com/4012-1 https://access.redhat.com/security/cve/CVE-2018-18521 https://bugzilla.redh • CWE-369: Divide By Zero •
CVE-2018-18284 – ghostscript: 1Policy operator allows a sandbox protection bypass
https://notcve.org/view.php?id=CVE-2018-18284
Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors involving the 1Policy operator. Artifex Ghostscript 9.25 y anteriores permite que los atacantes omitan un mecanismo de protección de sandbox mediante vectores relacionados con el operador 1Policy. • http://git.ghostscript.com/?p=ghostpdl.git%3Bh=8d19fdf63f91f50466b08f23e2d93d37a4c5ea0b http://www.openwall.com/lists/oss-security/2018/10/16/2 http://www.securityfocus.com/bid/107451 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.chromium.org/p/project-zero/issues/detail?id=1696 https://bugs.ghostscript.com/show_bug.cgi?id=699963 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44101 https://lists.debian.org/debian-lts-announce/2018/10/msg00013.html https: •
CVE-2018-18445 – kernel: Faulty computation of numberic bounds in the BPF verifier
https://notcve.org/view.php?id=CVE-2018-18445
In the Linux kernel 4.14.x, 4.15.x, 4.16.x, 4.17.x, and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandles 32-bit right shifts. En el kernel de Linux 4.14.x, 4.15.x, 4.16.x, 4.17.x y versiones 4.18.x anteriores a la 4.18.13, el cálculo incorrecto de enlaces numéricos en el verificador BPF permite accesos a la memoria fuera de límites debido a que adjust_scalar_min_max_vals en kernel/bpf/verifier.c gestiona de manera incorrecta los desplazamientos a la derecha de 32 bits. A security flaw was found in the Linux kernel in the adjust_scalar_min_max_vals() function in kernel/bpf/verifier.c. A faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because this function mishandles 32-bit right shifts. A local unprivileged user cannot leverage this flaw, but as a privileged user ("root") this can lead to a system panic and a denial of service or other unspecified impact. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b799207e1e1816b09e7a5920fbb2d5fcf6edd681 https://access.redhat.com/errata/RHSA-2019:0512 https://access.redhat.com/errata/RHSA-2019:0514 https://bugs.chromium.org/p/project-zero/issues/detail?id=1686 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.75 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.13 https://github.com/torvalds/linux/commit/b799207e1e1816b09e7a5920fbb2d5fcf6edd681 https:/ • CWE-125: Out-of-bounds Read •
CVE-2018-3136 – OpenJDK: Incorrect handling of unsigned attributes in signed Jar manifests (Security, 8194534)
https://notcve.org/view.php?id=CVE-2018-3136
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 6u201, 7u191, 8u182 and 11; Java SE Embedded: 8u181. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data. • http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/105601 http://www.securitytracker.com/id/1041889 https://access.redhat.com/errata/RHSA-2018:2942 https://access.redhat.com/errata/RHSA-2018:2943 https://access.redhat.com/errata/RHSA-2018:3000 https://access.redhat.com/errata/RHSA-2018:3001 https://access.redhat.com/errata/RHSA-2018:3002 https://access.redhat.com/errata/RHSA-2018:3003 https://access.redhat.com/errata/ • CWE-347: Improper Verification of Cryptographic Signature •
