StatementRed Hat does not consider crash of client application, using regcomp() or regexec() routines on untrusted input without preliminary checking the input for the sanity, to be a security issue (the described deficiency implies and is a known limitation of the glibc regular expression engine implementation). The expressions can be modified to avoid quantification nesting, or program modified to limit size of input passed to regular expression engine. We do not currently plan to fix these flaws. If more information becomes available at a future date, we may revisit these issues.
