There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to
    3.17.2,Oj::Parser#parse is vulnerable to a heap use-after-free when a SAJ/SAJ2 callback mutates the input
    JSON string during parsing. The C engine holds a raw const byte * pointer into the Ruby string's internal
    buffer. If a callback (e.g. hash_start) resizes the string — for example by calling String#replace with a
    longer value — Ruby reallocates the string buffer and frees the old one. The C parser's pointer is left
    dangling; the next character read at parser.c:607 is a use-after-free. This issue has been fixed in
    version 3.17.2. (CVE-2026-54898)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the rubygem package has been released.

The remote Debian 12 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4803 advisory.
