Description Josh Bressers 2005-03-31 14:18:18 UTC
There is a very obvious buffer overflow in ieee_putascii()

(code truncated)

static void ieee_putascii(char *format, ...)
    char buffer[256];
    vsprintf(buffer, format, ap);

At the very least it should be using a vsnprintf.

This issue should also affect RHEL2.1 and RHEL3

Comment 2 Jindrich Novy 2005-04-15 13:02:49 UTC
