This release provides Perl 5.24.4 that fixes a heap buffer overflow in the pack() function and two overflows in the regular expression engine.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1192 advisory.

    Perl is a high-level programming language that is commonly used for system administration utilities and     web programming.

    Security Fix(es):

    * perl: heap write overflow in regcomp.c (CVE-2018-6797)

    * perl: heap read overflow in regexec.c (CVE-2018-6798)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank Perl 5 Porters for reporting these issues. Upstream acknowledges Brian     Carpenter as the original reporter of CVE-2018-6797; and Nguyen Duc Manh as the original reporter of     CVE-2018-6798.

This update for perl fixes the following issues :

These security issue were fixed :

CVE-2018-6913: Fixed space calculation issues in pp_pack.c (bsc#1082216).

CVE-2018-6798: Fixed heap buffer overflow in regexec.c (bsc#1082233).

CVE-2018-6797: Fixed sharp-s regexp overflow (bsc#1082234).

CVE-2018-12015: The Archive::Tar module allowed remote attackers to bypass a directory-traversal protection mechanism and overwrite arbitrary files (bsc#1096718)

The update package also includes non-security fixes. See advisory for details.

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has perl packages installed that are affected by multiple vulnerabilities:

  - 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. (CVE-2018-6913)

  - Directory traversal vulnerability in the Archive::Tar Perl module 1.36 and earlier allows user-assisted     remote attackers to overwrite arbitrary files via a TAR archive that contains a file whose name is an     absolute path or has .. sequences. (CVE-2007-4829)

  - The rmtree function in lib/File/Path.pm in Perl 5.10 does not properly check permissions before performing     a chmod, which allows local users to modify the permissions of arbitrary files via a symlink attack, a     different vulnerability than CVE-2005-0448 and CVE-2004-0452. (CVE-2008-2827)

  - Perl 5.10.1 allows context-dependent attackers to cause a denial of service (application crash) via a     UTF-8 character with a large, invalid codepoint, which is not properly handled during a regular-expression     match. (CVE-2009-3626)

  - The bsd_glob function in the File::Glob module for Perl before 5.14.2 allows context-dependent attackers     to cause a denial of service (crash) via a glob expression with the GLOB_ALTDIRFUNC flag, which triggers     an uninitialized pointer dereference. (CVE-2011-2728)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3625-1 advisory.

    It was discovered that Perl incorrectly handled certain regular expressions. An attacker could possibly     use this issue to cause Perl to hang, resulting in a denial of service. This issue only affected Ubuntu     14.04 LTS. (CVE-2015-8853)

    It was discovered that Perl incorrectly loaded libraries from the current working directory. A local     attacker could possibly use this issue to execute arbitrary code. This issue only affected Ubuntu 14.04     LTS and Ubuntu 16.04 LTS. (CVE-2016-6185)

    It was discovered that Perl incorrectly handled the rmtree and remove_tree functions. A local attacker     could possibly use this issue to set the mode on arbitrary files. This issue only affected Ubuntu 14.04     LTS and Ubuntu 16.04 LTS. (CVE-2017-6512)

    Brian Carpenter discovered that Perl incorrectly handled certain regular expressions. An attacker could     use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue has only been addressed in Ubuntu 16.04 LTS and Ubuntu 17.10. (CVE-2018-6797)

    Nguyen Duc Manh discovered that Perl incorrectly handled certain regular expressions. An attacker could     use this issue to cause Perl to crash, resulting in a denial of service. This issue only affected Ubuntu     16.04 LTS and Ubuntu 17.10. (CVE-2018-6798)

    GwanYeong Kim discovered that Perl incorrectly handled certain data when using the pack function. An     attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2018-6913)
