tag_insight = "An editorial mistake resulted in DSA-1556-1 not correctly applying the
required change, making it ineffective.  This DSA has been reissued as
DSA-1556-2.  We apologize for the inconvenience.  The text of the
original DSA follows.

It has been discovered that the Perl interpreter may encounter a buffer
overflow condition when compiling certain regular expressions containing
Unicode characters.  This also happens if the offending characters are
contained in a variable reference protected by the \Q...\E quoting
construct.  When encountering this condition, the Perl interpreter
typically crashes, but arbitrary code execution cannot be ruled out.

For the stable distribution (etch), this problem has been fixed in
version 5.8.8-7etch3.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your perl packages.";
