AI Analysis
Technical Summary
The vulnerability CVE-2026-3505 in BC-JAVA's bcpg module allows an unauthenticated remote attacker to cause memory exhaustion by submitting a specially crafted PGP AEAD message containing an unbounded chunk size. This leads to uncontrolled allocation of memory resources in the JVM, resulting in denial of service. The issue affects BC-JAVA versions from 1.74 before 1.80.2, from 1.81 before 1.81.1, and from 1.82 before 1.84. The flaw is linked to program files AEADEncDataPacket.Java, BcAEADUtil.Java, JceAEADUtil.Java, and OperatorHelper.Java. Red Hat has published advisories and security updates addressing this vulnerability, recommending payload size enforcement and JVM memory quotas as mitigations.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to cause excessive memory consumption in the JVM, leading to denial of service and loss of system availability. There is no impact on confidentiality or integrity, but the availability impact is high.
Mitigation Recommendations
A security update fixing this vulnerability is available from Red Hat and should be applied. Additionally, enforce payload size limits on all incoming PGP messages before processing them. Applying memory quotas to the JVM or container environment can help prevent complete system outages in case of memory exhaustion. Follow vendor advisories for patch application and mitigation guidance.
