Date: Mon, 06 Oct 2014 18:29:05 -0700 From: Mick Ayzenberg <mick@...avusecurity.com> To: fulldisclosure@...lists.org Subject: [FD] CVE-2014-6251 : Stack Overflow in CPUMiner When Submitting Upstream Work Vulnerability title: Stack Overflow in CPUMiner When Submitting Upstream Work CVE: CVE-2014-6251 Affected version: CPUMiner before 2.4.1 Reported by: Mick Ayzenberg of Deja vu Security Details: A malicious pool or an attacker who is in the middle of a valid stratum connection can respond to a 'mining.subscribe' and instruct a miner to use a large nonce2 length. The attacker can then instruct the miner to generate blocks with a standard 'mining.notify' request. Once the miner has discovered a valid block it will attempt to copy this large nonce into a fixed size character array and overflow into stack memory. _______________________________________________ Sent through the Full Disclosure mailing list http://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
