CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 0CVE-2018-6798 – perl: heap read overflow in regexec.c
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-2018-10119
sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format. sot/source/sdstor/stgstrms.cxx en LibreOffice, en versiones anteriores a la 5.4.5.1 y versiones 6.x anteriores a la 6.0.1.1, emplea un tipo de datos incorrecto en la clase StgSmallStrm. Esto permite que atacantes remotos provoquen una denegación de servicio (uso de memoria previamente liberada con acceso de escritura) o que puedan causar otro tipo de impacto sin especificar mediante un documento manipulado que emplea el formato contenedor de archivo ole2 de almacenamiento estructurado. • https://access.redhat.com/errata/RHSA-2018:3054 https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=5747 https://gerrit.libreoffice.org/#/c/48751 https://gerrit.libreoffice.org/#/c/48756 https://gerrit.libreoffice.org/#/c/48757 https://gerrit.libreoffice.org/#/c/48758 https://gerrit.libreoffice.org/gitweb?p=core.git%3Ba=commit%3Bh=fdd41c995d1f719e92c6f083e780226114762f05 https://lists.debian.org/debian-lts-announce/2018/04/msg00021.html https://usn.ubuntu.com/3883- • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-10120
The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows remote attackers to cause a denial of service (heap-based buffer overflow with write access) or possibly have unspecified other impact via a crafted document that contains a certain Microsoft Word record. La función SwCTBWrapper::Read en sw/source/filter/ww8/ww8toolbar.cxx en LibreOffice, en versiones anteriores a la 5.4.6.1 y versiones 6.x anteriores a la 6.0.2.1, no valida un índice de personalizaciones.

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 •
