org.bouncycastle/bcpg-fips: org.bouncycastle/bcpg-jdk15on: org.bouncycastle/bcpg-jdk18on: Bouncy Castle for Java: Denial of Service due to unbounded OpenPGP user-attribute subpacket length

A flaw was found in Bouncy Castle for Java. The software's processing of OpenPGP user-attribute subpackets does not properly limit their length, bounding them only by the Java Virtual Machine JVM maximum memory. A remote attacker could exploit this by sending a specially crafted OpenPGP message,...
