Mozilla beats rivals, patches Firefox’s Pwn2Own bug
Mozilla last week patched a Firefox vulnerability just a day after it was revealed during Pwn2Own, the first vendor to fix a flaw disclosed at the hacking contest.
“Congrats to #Mozilla for being the first vendor to patch vuln[erability] disclosed during #Pwn2Own,” tweeted the Zero Day Initiative (ZDI) Monday. ZDI, the bug brokerage run by Trend Micro, sponsored Pwn2Own.
Mozilla released Firefox 52.0.1 on Friday, March 17, with a patch for the integer overflow bug that Chaitin Security Research Lab leveraged in an exploit at Pwn2Own on Thursday, March 16. The Beijing-based group was awarded $30,000 by ZDI for the exploit, which combined the Firefox bug with one in the Windows kernel.
