Deserialization vulnerability in lintian through 2.5.50.3 allows attackers to trigger code execution by requesting a review of a source package with a crafted YAML file.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Lintian Debian * 2.5.50.3 (including)
Lintian Ubuntu devel *
Lintian Ubuntu esm-infra/xenial *
Lintian Ubuntu upstream *
Lintian Ubuntu xenial *
Lintian Ubuntu yakkety *
Lintian Ubuntu zesty *

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
