CVE-2012-2808: Google Bionic

Medium severity, CVSS 5.0. EPSS: 1.3% chance of exploitation in the next 30 days.

The PRNG implementation in the DNS resolver in Bionic in Android before 4.1.1 incorrectly uses time and PID information during the generation of 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-2015-0800.

Affected products

• Google Bionic: up to and including 4.1.0
