K15867 : Perl vulnerabilities CVE-2012-5195, CVE-2012-5526, CVE-2012-6329, and CVE-2013-1667

Security Advisory Description

• CVE-2012-5195

Heap-based buffer overflow in the Perl_repeatcpy function in util.c in Perl 5.12.x before 5.12.5, 5.14.x before 5.14.3, and 5.15.x before 15.15.5 allows context-dependent attackers to cause a denial of service (memory consumption and crash) or possibly execute arbitrary code via the ‘x’ string repeat operator.

• CVE-2012-5526

CGI.pm module before 3.63 for Perl does not properly escape newlines in (1) Set-Cookie or (2) P3P headers, which might allow remote attackers to inject arbitrary headers into responses from applications that use CGI.pm.

• CVE-2012-6329

The _compile function in Maketext.pm in the Locale::Maketext implementation in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation, which allows context-dependent attackers to execute arbitrary commands via crafted input to an application that accepts translation strings from users, as demonstrated by the TWiki application before 5.1.3, and the Foswiki application 1.0.x through 1.0.10 and 1.1.x through 1.1.6.

• CVE-2013-1667

The rehash mechanism in Perl 5.8.2 through 5.16.x allows context-dependent attackers to cause a denial of service (memory consumption and crash) via a crafted hash key.
Impact
The Perl binary and its library are only available to users with access to the command line on the BIG-IP system. If exploited, these vulnerabilities may allow an attacker to gain knowledge of sensitive information, manipulate certain data, or remotely execute code.
