Detailsinfo

A vulnerability was found in MidnightBSD mport up to 2.7.7. It has been rated as problematic. Affected by this issue is the function audit_package of the file mport/mport.c of the component Audit Command. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is integrity. CVE summarizes:

mport is the MidnightBSD Package Manager. Prior to 2.7.8, the audit command in mport/mport.c computed option-adjusted local_argv and local_argc values but passed the original argument entry to audit_package(). When an operator or automation used an option such as -r before a package name, stale optind state and the unadjusted argument could cause mport to audit the option token instead of the requested package, producing a false-negative or useless result that could leave a vulnerable package unidentified. The corrected parsing resets optind and optreset before using the adjusted local arguments. This issue is fixed in version 2.7.8.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-54577 since 06/15/2026. The exploitation is known to be easy. The attack may be launched remotely. There are known technical details, but no exploit is available.
