Icecast 1.3.7 and 1.3.8 beta2 buffer overflow

by evilnop on January 23rd, 2001 |CyRaX| from PKcrew has discoverd buffer overflow in icecast 1.3.7 and 1.3.8 beta2 streaming audio server....

Versions of icecast up to and including 1.3.8 beta2 exhibit a format string vulnerability in the print_client() function of utility.c.
An insecurely-structured call to fd_write() directly passes user supplied characters as part of the format string to a *printf function. As a result, a malicious user can cause the *printf function to overwrite memory at possibly arbitrary addresses. This type of vulnerability can be exploited by a remote attacker to execute arbitrary code on the victim host.
