CVE-2007-4657 Detail

Vendor Statements (disclaimer)

Official Statement from Red Hat (09/05/2007)

The only effect of this bug is to cause the process to read from a random segment of memory, if a large "length" parameter is passed to the strspn/strcspn function, which is under the control of the script author. This bug has no security impact.
