https://notcve.org/view.php?id=CVE-2018-6797
An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written. Se ha descubierto un problema en Perl 5.26. Una expresión regular manipulada puede provocar un desbordamiento de búfer basado en memoria dinámica (heap), con control sobre los bytes que se escriben. A heap buffer write overflow, with control over the bytes written, was found in the way regular expressions employing Unicode rules are compiled. • http://www.securitytracker.com/id/1040681 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2018:1192 https://rt.perl.org/Public/Bug/Display.html?id=132227 https://security.gentoo.org/glsa/201909-01 https://usn.ubuntu.com/3625-1 https://www.debian.org/security/2018/dsa-4172 https://www.oracle.com/security-alerts/cpujul2020.html https://access.redhat.com/security/cve/CVE-2018-6797 https://bugzilla.redhat.com/show_bug.cgi?id=1547783 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-6798
An issue was discovered in Perl 5.22 through 5.26. Matching a crafted locale dependent regular expression can cause a heap-based buffer over-read and potentially information disclosure. Se ha descubierto un problema en Perl, de la versión 5.22 a la 5.26. Si se hace que coincida una expresión regular dependiente de una locale manipulada, se puede provocar una sobrelectura de búfer basada en memoria dinámica (heap) y una potencial divulgación de información. A heap buffer over read flaw was found in the way Perl regular expression engine handled inputs with invalid UTF-8 characters. • http://www.securitytracker.com/id/1040681 https://access.redhat.com/errata/RHSA-2018:1192 https://rt.perl.org/Public/Bug/Display.html?id=132063 https://security.gentoo.org/glsa/201909-01 https://usn.ubuntu.com/3625-1 https://www.debian.org/security/2018/dsa-4172 https://www.oracle.com/security-alerts/cpujul2020.html https://access.redhat.com/security/cve/CVE-2018-6798 https://bugzilla.redhat.com/show_bug.cgi?id=1547779 • CWE-125: Out-of-bounds Read •

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 •

https://notcve.org/view.php?id=CVE-2018-1000156
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') •
