Description Vladimir Vasilev 2026-09-09 07:04:22 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

In the opam package before 2.5.2 for OCaml, the sandbox protection mechanism can be bypassed because symlinks are mishandled during use of .install files.
Comment 1 Jerry James 2026-09-09 17:12:48 UTC 
No current Fedora release has opam before 2.5.2.  We are on 2.5.2 in F43+.
