RHEL 8 : perl (Unpatched Vulnerability)

high Nessus Plugin ID 199784

Synopsis

The remote Red Hat 8 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- perl: corruption of intermediate language state of compiled regular expression due to integer overflow leads to DoS (CVE-2020-10878)

- Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. (CVE-2020-10543)

- regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls. (CVE-2020-12723)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
