Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

bibtex-ruby versions before 5.1.0 are vulnerable to OS command injection, because user-supplied input is passed directly to Kernel.open through BibTeX.open. The source does not describe the exact conditions under which an attacker can supply that input, but successful exploitation would let them run shell commands on the system. Upgrade to bibtex-ruby 5.1.0 or later.
