https://www.bouncycastle.org/latest_releases.htmlDEBIANBUG: [1070655] (CVE-2024-29857)

An issue was discovered in Bouncy Castle Java Cryptography APIs before BC 1.78. When endpoint identification is enabled in the BCJSSE and an SSL socket is created without an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address in some situations, opening up a possibility of DNS poisoning. (CVE-2024-34447)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update bouncycastle --releasever 2023.4.20240611' to update your system.
