**Name of the Vulnerable Software and Affected Versions** Perl versions 5.8.6 through 5.9.2 **Description** The issue is related to an integer overflow in the format string functionality, specifically in the `Perl sv vcatpvfn` function. This allows attackers to potentially overwrite arbitrary memory and execute arbitrary code by using format string specifiers with large values, causing an integer wrap that leads to a buffer overflow. **Recommendations** For Perl versions 5.8.6 through 5.9.2, consider applying configuration changes to restrict the use of format string specifiers until a patch is available. As a temporary workaround, restrict access to the `Perl sv vcatpvfn` function to minimize the risk of exploitation. Avoid using large values in format string specifiers in the affected Perl applications until the issue is resolved.

**Name of the Vulnerable Software and Affected Versions** Webmin versions prior to 1.250 Usermin versions prior to 1.180 **Description** A format string issue in the miniserv.pl Perl web server allows remote attackers to cause a denial of service or possibly execute arbitrary code via format string specifiers in the `username` parameter to the login form, which is used in a syslog call. **Recommendations** For Webmin versions prior to 1.250, update to version 1.250 or later to resolve the issue. For Usermin versions prior to 1.180, update to version 1.180 or later to resolve the issue. As a temporary workaround, consider disabling syslog logging in miniserv.pl until a patch is available. Restrict access to the login form to minimize the risk of exploitation.
