    Package        : opam     Version        : 2.1.2-1+deb12u2     CVE ID         : CVE-2026-57825

    Kate Deplaix reported that .install file directives were insufficiently     restricted in OPAM, a package manager for OCaml. Installing files     through .install files did not check symlinks resolution on the target     path, which could result in directory traversal out of the package area.

    For Debian 12 bookworm, this problem has been fixed in version     2.1.2-1+deb12u2.

    We recommend that you upgrade your opam packages.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the b478ff13-7f6e-11f1-b594-3c7c3fba4204 advisory.

    The OCaml Team reports:
    Installing files through .install files do not check symlinks resolution of the target path, and so can     bypass sandboxing.
