high Nessus Plugin ID 144314

Synopsis

The remote AIX host is missing a security patch.

Description

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10543 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10543 Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. Perl before 5.30.3 has an integer overflow related to mishandling of a 'PL_regkind[OP(n)] == NOTHING' situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

Solution

Install the appropriate interim fix.
