Amazon Linux 2023 Security Advisory: ALAS2023-2024-636
Advisory Released Date: 2024-06-14
Advisory Updated Date: 2024-06-14
Severity:
Medium
Issue Overview:
An issue was discovered in ECCurve.java and ECCurve.cs in Bouncy Castle Java (BC Java) before 1.78, BC Java LTS before 2.73.6, BC-FJA before 1.0.2.5, and BC C# .Net before 2.3.1. Importing an EC certificate with crafted F2m parameters can lead to excessive CPU consumption during the evaluation of the curve parameters. (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)
