CVE-2006-7226: Double Free
First published: Thu Nov 15 2007(Updated: )
From pcre changelog, version 6.7: 26. If a subpattern containing a named recursion or subroutine reference such as (?P>B) was quantified, for example (xxx(?P>B)){3}, the calculation of the space required for the compiled pattern went wrong and gave too small a value. Depending on the environment, this could lead to "Failed: internal error: code overflow at offset 49" or "glibc detected double free or corruption" errors. Acknowledgements: Red Hat would like to thank Ludwig Nussel for reporting this issue.
