## Summary Two vulnerabilities have been found in Rekor types for archive files JARs and APKs, where Rekor would crash due to out of memory conditions caused by reading archive metadata files into memory without checking their sizes first causing a Denial of Service of Rekor. These vulnerabilities were found through fuzzing with [OSS-Fuzz](https://google.github.io/oss-fuzz/). ## Vulnerability 1: OOM due to large files in META-INF directory of JAR files. ### Summary Verification of a JAR file submitted to Rekor can cause an out of memory crash if files within the META-INF directory of the JAR are sufficiently large. ### Details As part of verifying a JAR file, Rekor uses the [relic library](http://github.com/sassoftware/relic) to check that the JAR is signed, the signature verifies, and that the hashes in the signed manifest are all valid. This library function reads files within META-INF/ into memory without checking their sizes, resulting in an OOM if the uncompressed file is suffi...
