Description Josh Bressers 2005-03-31 14:20:08 UTC
+++ This bug was initially created as a clone of Bug #152962 +++

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.

Comment 1 Josh Bressers 2005-03-31 14:20:41 UTC
This issue should also affect FC2

Comment 2 Jindrich Novy 2005-04-15 13:04:22 UTC
Applied and built in FC3. Patch added to the fedora-legacy bug for this and
CAN-2004-1287 issue.
