perl, webmin, usermin -- perl format string integer wrap vulnerability

Description:

The Perl Development page reports:

Dyad Security recently released a security advisory explaining how in certain cases, a carefully crafted format string passed to sprintf can cause a buffer overflow. This buffer overflow can then be used by an attacker to execute code on the machine. This was discovered in the context of a design problem with the Webmin administration package that allowed a malicious user to pass unchecked data into sprintf.
