Severity: important

Hi,

the following vulnerability was published for cgminer.

CVE-2014-6251[0]:
| Stack-based buffer overflow in CPUMiner before 2.4.1 allows remote
| attackers to have an unspecified impact by sending a mining.subscribe
| response with a large nonce2 length, then triggering the overflow with
| a mining.notify request.

Details are sparse, and note that the report is about cpuminer rather
than cgminer, but since the two share a lot of code, I couldn't easily
rule out cgminer being affected, so some research needs to be done.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.
