Security Bulletin: Astronomer with IBM is vulnerable to denial of service due to the resolv package (CVE-2025-24294)

Summary Resolv is used by Astronomer with IBM as part of the DNS functionality. Vulnerability Details CVEID:CVE-2025-24294 DESCRIPTION: The attack vector is a potential Denial of Service DoS. The vulnerability is caused by an insufficient check on the length of a decompressed domain name within a...

Denial Of Service (DoS)

resolv library is vulnerable to Denial Of Service DoS. The vulnerability is due to insufficient validation of the length of a decompressed domain name in a DNS packet, which allows an attacker to craft a maliciously compressed DNS packet that consumes excessive CPU during name decompression...

UBUNTU-CVE-2017-17790

The lazyinitialize function in lib/resolv.rb in Ruby through 2.4.3 uses Kernelopen, which might allow Command Injection attacks, as demonstrated by a Resolv::Hosts::new argument beginning with a '|' character, a different vulnerability than CVE-2017-17405. NOTE: situations with untrusted input ma...
