Synopsis

The remote Red Hat host is missing one or more security updates for rh-perl526-perl.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:0001 advisory.

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

The following packages have been upgraded to a later upstream version: rh-perl526-perl (5.26.3), rh- perl526-perl-Module-CoreList (5.20181130). (BZ#1658969)

Security Fix(es):

* perl: Integer overflow leading to buffer overflow in Perl_my_setenv() (CVE-2018-18311)

* perl: Heap-based buffer overflow in S_handle_regex_sets() (CVE-2018-18312)

* perl: Heap-based buffer overflow in S_regatom() (CVE-2018-18314)

* perl: Heap-based buffer read overflow in S_grok_bslash_N() (CVE-2018-18313)

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 the Perl project for reporting these issues. Upstream acknowledges Jayakrishna Menon as the original reporter of CVE-2018-18311; Eiichi Tsukata as the original reporter of CVE-2018-18312 and CVE-2018-18313; and Jakub Wilk as the original reporter of CVE-2018-18314.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rh-perl526-perl package based on the guidance in RHSA-2019:0001.
