CVE-2024-29857
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
