Two vulnerabilities were discovered in the implementation of the Perl programming language :
CVE-2012-5195 The ‘x’ operator could cause the Perl interpreter to crash if very long strings were created.
CVE-2012-5526 The CGI module does not properly escape LF characters in the Set-Cookie and P3P headers.
In addition, this update adds a warning to the Storable documentation that this package is not suitable for deserializing untrusted data.
