Hi, we have found Out Of Memory error while fuzzing Asn1Decoder for LDAP messages. Steps to reproduce: 1. Download Apache Directory LDAP API v2.1.6: {code:java} wget wget https://github.com/apache/directory-ldap-api/archive/refs/tags/2.1.6.tar.gz tar xf 2.1.6.tar.gz && rm 2.1.6.tar.gz{code} 2. Compile the project (we used jdk-11 and mvn-3.9.6): {code:java} cd directory-ldap-api-2.1.6 mvn clean package{code} 3. Get the reproducer: {code:java} mkdir fuzz && cd fuzz mv <path/to/reproducer>/OutOfMemoryReproducer.java .{code} 4. Compile the reproducer {code:java} javac -cp ../asn1/ber/target/classes/:../asn1/api/target/classes/:../ldap/codec/core/target/classes/:../ldap/model/target/classes/:../ldap/codec/core/target/classes/ ./OutOfMemoryReproducer.java{code} 5. Reproduce the error: {code:java} java -Xmx2000m -cp .:../asn1/ber/target/classes/:../asn1/api/target/classes/:../ldap/codec/core/target/classes/:../ldap/model/target/classes/:../ldap/codec/core/target/classes/:../util/target/classes/:../util/target/classes/:../integ-osgi/target/dependency/slf4j-api-1.7.36.jar:../i18n/target/classes/:../integ-osgi/target/dependency/mina-core-2.2.3.jar OutOfMemoryReproducer{code} We think that 2000 MB is a reasonable limit and the program should not take more.
