0day in Firefox from ToorCon '06
CNet is writing about some 0day vulnerabilities in Firefox that were
demonstrated at ToorCon '06 by Mischa Spiegelmock and Andrew Wbeelsoi:
http://news.zdnet.com/2100-1009_22-6121608.html
Mischa and Andrew also claim to have found about 30 0day vulnerabilities
in Firefox. The article mention that the vulnerabilities from the
presentation are specific to Firefox's implementation of Javascript and
hints that they are stack overflows. On the other hand, the recent
security-related Mozilla commits following the presentation deal with
improper validation of scope chain lookups in jsxml.c, jsinterp.c and
jsiter.c, which could allow injecting content into the Chrome context.
We'll probably see a security release of Firefox in the next week, but
in the mean time I have put a couple of links to the code diff's that
fix these vulnerabilities at
