Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for perl fixes the following issues :

CVE-2020-10543: Fixed a heap buffer overflow in regular expression compiler which could have allowed overwriting of allocated memory with attacker's data (bsc#1171863).

CVE-2020-10878: Fixed multiple integer overflows which could have allowed the insertion of instructions into the compiled form of Perl regular expression (bsc#1171864).

CVE-2020-12723: Fixed an attacker's corruption of the intermediate language state of a compiled regular expression (bsc#1171866).

Fixed a bad warning in features.ph (bsc#1172348).
