CVE-2024-52616: Red Hat Enterprise Linux 7

Medium severity, CVSS 5.3. EPSS: 0.7% chance of exploitation in the next 30 days.

A flaw was found in the Avahi-daemon, where it initializes DNS transaction IDs randomly only once at startup, incrementing them sequentially after that. This predictable behavior facilitates DNS spoofing attacks, allowing attackers to guess transaction IDs.

• Red Hat Red Hat Enterprise Linux 9: before 0:0.8-22.el9_6 (fixed in 0:0.8-22.el9_6)
