Weaknesses
CWE-292

Description

eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a "TuDoor" attack. In other words, dnspython does not have the preferred behavior in which the DNS name resolution algorithm would proceed, within the full time window, in order to wait for a valid packet. NOTE: dnspython 2.6.0 is unusable for a different reason that was addressed in 2.6.1.

Affected configurations

• eventlet eventlet (< 0.35.2) • dnspython dnspython (< 2.6.0) • fedoraproject fedora 38 • fedoraproject fedora 39 • fedoraproject fedora 40 • netapp bootstrap os
