About this tag
The erlang jose tag covers discussions about the JOSE (JSON Object Signing and Encryption) library for Erlang and Elixir, particularly around security vulnerabilities. A key topic is CVE-2023-50966, which affects erlang jose versions through 1.11.6. This vulnerability allows attackers to cause denial of service by supplying maliciously large PBES2 iteration counts (p2c header) during JWE decryption, leading to excessive CPU consumption. The fix was released in version 1.11.7. Microsoft has acknowledged that Azure Linux includes this library and is potentially affected, with plans to update CVE/VEX mappings if other Microsoft products are identified as carriers. The tag is relevant for developers and IT professionals managing Erlang/Elixir environments or Azure Linux deployments.
