When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-502","CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/google/guava/commit/b931fe9d6d5cf00bc55714ad3308d086f71850fe","tags":[]},{"url":"https://github.com/google/guava/releases/tag/v33.7.2","tags":[]},{"url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","tags":[]},{"url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","tags":[]}],"exploitRefs":[{"url":"https://github.com/google/guava/commit/b931fe9d6d5cf00bc55714ad3308d086f71850fe","tags":[]},{"url":"https://github.com/google/guava/releases/tag/v33.7.2","tags":[]},{"url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","tags":[]},{"url":"https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","tags":[]}],"hasPoc":true,"ai":null}
