Perl before 5.26.3 has a buffer over-read via a crafted regular expression that triggers disclosure of sensitive information from process memory. Perl, en versiones anteriores a la 5.26.3, tiene una sobrelectura de búfer mediante una expresión regular manipulada que desencadena la divulgación de información sensible de la memoria del proceso. • http://seclists.org/fulldisclosure/2019/Mar/49 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=1646738 https://github.com/Perl/perl5/commit/43b2f4ef399e2fd7240b4eeb0658686ad95f8e62 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& • CWE-125: Out-of-bounds Read •

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') •
