UnknownEPSS 1.68%

Last modified Jun 17, 2026

CVE-2015-0800 is a vulnerability of currently unknown severity. The PRNG implementation in the DNS resolver in Mozilla Firefox (aka Fennec) before 37.0 on Android does not properly generate random numbers for query ID values and UDP source ports, which makes it easier for remote attackers to spoof DNS responses by guessing these numbers, a related issue to CVE-2012-2808.. EPSS estimates a 1.68% chance of exploitation in the next 30 days.
