========================================================================== Ubuntu Security Notice USN-2916-1 March 02, 2016
perl vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in Perl.
Software Description: - perl: Practical Extraction and Report Language
Details:
It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-7422)
Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker could use this issue to cause Perl to consume memory and crash, resulting in a denial of service. (CVE-2014-4330)
Stephane Chazelas discovered that Perl incorrectly handled duplicate environment variables. An attacker could possibly use this issue to bypass the taint protection mechanism. (CVE-2016-2381)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.10: perl 5.20.2-6ubuntu0.2
Ubuntu 14.04 LTS: perl 5.18.2-2ubuntu1.1
Ubuntu 12.04 LTS: perl 5.14.2-6ubuntu2.5
In general, a standard system update will make all the necessary changes.
