CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 0CVE-2018-1100 – zsh: buffer overflow in utils.c:checkmailpath() can lead to local arbitrary code execution
https://notcve.org/view.php?id=CVE-2018-1100
zsh through version 5.4.2 is vulnerable to a stack-based buffer overflow in the utils.c:checkmailpath function. A local attacker could exploit this to execute arbitrary code in the context of another user. zsh hasta la versión 5.4.2 es vulnerable a un desbordamiento de búfer basado en pila en la función utils.c:checkmailpath. Un atacante local podría explotarlo para ejecutar código arbitrario en el contexto de otro usuario. A buffer overflow flaw was found in the zsh shell check path functionality. A local, unprivileged user can create a specially crafted message file, which, if used to set a custom "you have new mail" message, leads to code execution in the context of the user who receives the message. • https://access.redhat.com/errata/RHSA-2018:1932 https://access.redhat.com/errata/RHSA-2018:3073 https://bugzilla.redhat.com/show_bug.cgi?id=1563395 https://lists.debian.org/debian-lts-announce/2020/12/msg00000.html https://security.gentoo.org/glsa/201805-10 https://sourceforge.net/p/zsh/code/ci/31f72205630687c1cef89347863aab355296a27f https://usn.ubuntu.com/3764-1 https://access.redhat.com/security/cve/CVE-2018-1100 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time. La versión 2.7.6 de GNU Patch contiene una vulnerabilidad de validación de entradas al procesar archivos patch; específicamente la invocación EDITOR_PROGRAM (usando ed) puede resultar en la ejecución de código. el ataque parece ser explotable mediante un archivo patch procesado mediante la utilidad patch. Esto es similar al CVE-2015-1418 de FreeBSD: aunque comparten un ancestro común, las bases de código han divergido con el tiempo. • http://packetstormsecurity.com/files/154124/GNU-patch-Command-Injection-Directory-Traversal.html http://rachelbythebay.com/w/2018/04/05/bangpatch https://access.redhat.com/errata/RHSA-2018:1199 https://access.redhat.com/errata/RHSA-2018:1200 https://access.redhat.com/errata/RHSA-2018:2091 https://access.redhat.com/errata/RHSA-2018:2092 https://access.redhat.com/errata/RHSA-2018:2093 https://access.redhat.com/errata/RHSA-2018:2094 https://access.redhat.com/errata/RHSA-2018:2095 ht • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 7.8EPSS: 0%CPEs: 21EXPL: 0CVE-2018-7566 – kernel: race condition in snd_seq_write() may lead to UAF or OOB-access
https://notcve.org/view.php?id=CVE-2018-7566
The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user. El kernel de Linux 4.15 tiene un desbordamiento de búfer mediante una operación de escritura ioctl SNDRV_SEQ_IOCTL_SET_CLIENT_POOL en /dev/snd/seq por un usuario local. ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. • http://lists.opensuse.org/opensuse-security-announce/2018-03/msg00067.html http://mailman.alsa-project.org/pipermail/alsa-devel/2018-February/132026.html http://www.securityfocus.com/bid/103605 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2019:1483 https://access.redhat.com/errata/RHSA-2019:1487 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2018-1083
Zsh before version 5.4.2-test-1 is vulnerable to a buffer overflow in the shell autocomplete functionality. A local unprivileged user can create a specially crafted directory path which leads to code execution in the context of the user who tries to use autocomplete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation. Zsh en versiones anteriores a la 5.4.2-test-1 es vulnerable a un desbordamiento de búfer en la funcionalidad de autocompletar del shell. Un usuario local sin privilegios puede crear una ruta de directorio especialmente manipulada que dé lugar a la ejecución de código en el contexto de un usuario que trata de emplear el autocompletado para crear un salto de directorio a la localización mencionada. • http://www.securityfocus.com/bid/103572 https://access.redhat.com/errata/RHSA-2018:1932 https://access.redhat.com/errata/RHSA-2018:3073 https://bugzilla.redhat.com/show_bug.cgi?id=1557382 https://lists.debian.org/debian-lts-announce/2018/03/msg00038.html https://lists.debian.org/debian-lts-announce/2020/12/msg00000.html https://security.gentoo.org/glsa/201805-10 https://sourceforge.net/p/zsh/code/ci/259ac472eac291c8c103c7a0d8a4eaf3c2942ed7 https://usn.ubuntu.com/3608-1 https:/& • 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') CWE-121: Stack-based Buffer Overflow •
