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 utf8 handling in perldoc by useing 'term' instead of 'man' (bsc#1170601).

Some packages make assumptions about the date and time they are built.
This update will solve the issues caused by calling the perl function timelocal expressing the year with two digit only instead of four digits. (bsc#1102840) (bsc#1160039)

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