Details

USN-4602-1 fixed several vulnerabilities in Perl. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

ManhND discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-10543)

Hugo van der Sanden and Slaven Rezic discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-10878)

Sergey Aleynikov discovered that Perl incorrectly handled certain regular expressions. In environments where untrusted regular expressions are evaluated, a remote attacker could possibly use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-12723)
