What it is

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.
