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,...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the readPacket method of UserAttributeSubpacketInputStream, which reads a 5-octet subpacket length up to Integer.MAXVALUE and allocates new bytebodyLen-1 after checking only against a limit...
