Vulnerability from variot - Updated: 2026-03-09 20:40

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. An attacker could exploit this vulnerability to cause a denial of service. 7.7) - ppc64, ppc64le, s390x, x86_64

8.2) - aarch64, noarch, ppc64le, s390x, x86_64

perl vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

Ubuntu 14.04 ESM
Ubuntu 12.04 ESM

Summary:

Several security issues were fixed in Perl.

Software Description: - perl: Practical Extraction and Report Language

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)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 ESM: perl 5.18.2-2ubuntu1.7+esm3

Ubuntu 12.04 ESM: perl 5.14.2-6ubuntu2.11

In general, a standard system update will make all the necessary changes. Description:
