Now, Opera is putting the tool to a similar use.
Opera noted in an advisory that the flaw could allow a hacker to execute code on the victim machine. A virtual function call on an invalid pointer, which may reference data crafted by the attacker, can be used to execute arbitrary code.
In a blog posted on Aug. 6, Snyder said she had communicated with Claudio Santambrogio, a test manager at Opera, and he told her that at that point they had found and fixed four flaws with the fuzzer.
"I am thrilled," wrote Snyder. "This is exactly what we hoped would happen. Hopefully, this will encourage other vendors to share their internal security tools with everyone so we call all make our software more secure."
