https://notcve.org/view.php?id=CVE-2018-18314
Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations. Perl, en versiones anteriores a la 5.26.3, tiene un desbordamiento de búfer mediante una expresión regular manipulada que desencadena operaciones inválidas de escritura. • http://www.securityfocus.com/bid/106145 http://www.securitytracker.com/id/1042181 https://access.redhat.com/errata/RHSA-2019:0001 https://access.redhat.com/errata/RHSA-2019:0010 https://bugzilla.redhat.com/show_bug.cgi?id=1646751 https://github.com/Perl/perl5/commit/19a498a461d7c81ae3507c450953d1148efecf4f https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RWQGEB543QN7SSBRKYJM6PSOC3RLYGSM https://metacpan.org/changes/release/SHAY/perl-5.26.3 https://rt.perl. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
CVSS: 7.5EPSS: 52%CPEs: 14EXPL: 1CVE-2018-12015 – perl: Directory traversal in Archive::Tar
https://notcve.org/view.php?id=CVE-2018-12015
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name. En Perl hasta la versión 5.26.2, el módulo Archive::Tar permite que atacantes remotos omitan un mecanismo de protección de salto de directorio y sobrescriban archivos arbitrarios mediante un archivo comprimido que contiene un symlink y un archivo normal con el mismo nombre. It was found that the Archive::Tar module did not properly sanitize symbolic links when extracting tar archives. An attacker, able to provide a specially crafted archive for processing, could use this flaw to write or overwrite arbitrary files in the context of the Perl interpreter. • http://seclists.org/fulldisclosure/2019/Mar/49 http://www.securityfocus.com/bid/104423 http://www.securitytracker.com/id/1041048 https://access.redhat.com/errata/RHSA-2019:2097 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900834 https://seclists.org/bugtraq/2019/Mar/42 https://security.netapp.com/advisory/ntap-20180927-0001 https://support.apple.com/kb/HT209600 https://usn.ubuntu.com/3684-1 https://usn.ubuntu.com/3684-2 https://www.debian.org/security/2018& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count. Desbordamiento de búfer basado en memoria dinámica (heap) en la función pack de Perl, en versiones anteriores a la 5.26.2, permite que atacantes dependientes del contexto ejecuten código arbitrario mediante un conteo de items largo. • http://www.securityfocus.com/bid/103953 http://www.securitytracker.com/id/1040681 https://lists.debian.org/debian-lts-announce/2018/04/msg00009.html https://rt.perl.org/Public/Bug/Display.html?id=131844 https://security.gentoo.org/glsa/201909-01 https://usn.ubuntu.com/3625-1 https://usn.ubuntu.com/3625-2 https://www.debian.org/security/2018/dsa-4172 https://www.oracle.com/security-alerts/cpujul2020.html • CWE-787: Out-of-bounds Write •

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 •
