CVE-2019-16159: Debian Linux

High severity, CVSS 7.5. EPSS: 3.2% chance of exploitation in the next 30 days.

BIRD Internet Routing Daemon 1.6.x through 1.6.7 and 2.x through 2.0.5 has a stack-based buffer overflow. The BGP daemon's support for RFC 8203 administrative shutdown communication messages included an incorrect logical expression when checking the validity of an input message. Sending a shutdown communication with a sufficient message length causes a four-byte overflow to occur while processing the message, where two of the overflow bytes are attacker-controlled and two are fixed.

Affected products

  • Debian Debian Linux: version 10.0 only
  • Fedoraproject Fedora: version 29 only; version 30 only
  • Nic Bird: from 1.6.0, up to and including 1.6.7; from 2.0.0, up to and including 2.0.5
