CVE-2026-54584: External Control of File Name or Path

mport is the MidnightBSD Package Manager. mport before 2.7.8 used TMPDIR while extracting package metafiles, including when running as root or in setuid/setgid contexts. An attacker able to control the environment for a privileged mport invocation could redirect temporary metadata extraction to a...

CVE-2026-54579

mport is the MidnightBSD Package Manager. Prior to 2.7.8, ping in libmport/ping.c accepted ICMP replies without validating icmpid or icmpseq and parsed the reply using a fixed IP-header offset instead of iphl. A network attacker able to inject or spoof visible ICMP replies could influence mirror...

CVE-2026-54576

mport is the MidnightBSD Package Manager. Prior to 2.7.8, doactualinstall in libmport/bundlereadinstallpkg.c used path-based lstat, chown, stat, and chmod operations while installing package files. A local attacker with write access to a target directory could replace a checked file with a symlin...

CVE-2026-54587

mport is the MidnightBSD Package Manager. Prior to 2.7.8, directory assets handled as ASSETDIR or ASSETDIROWNERMODE in libmport/bundlereadinstallpkg.c used path-based mportmkdirp, ownership, and permission operations. A local attacker able to modify part of the target installation tree could use...

CVE-2026-54575

mport is the MidnightBSD Package Manager. Prior to 2.7.8, privileged package fetch and cache-cleaning operations used race-prone path handling across libmport/fetch.c, libmport/clean.c, libmport/util.c, libmport/bundlereadinstallpkg.c, libmport/deleteprimative.c, and...

CVE-2026-54578

mport is the MidnightBSD Package Manager. Prior to 2.7.8, mportverifypackage in libmport/verify.c could continue after MD5File or SHA256File failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed...

CVE-2026-54586

mport is the MidnightBSD Package Manager. Prior to 2.7.8, the mportfetchindex, mportfetchbootstrapindex, and mportfetchbundle paths in libmport/fetch.c accepted non-HTTPS repository and package mirror URLs without a urlishttps enforcement check. When a cleartext URL was configured or returned by...

CVE-2026-54585

mport is the MidnightBSD Package Manager. Prior to 2.7.8, createsamplefile in libmport/bundlereadinstallpkg.c did not constrain absolute source and destination paths from the sample-file manifest directive to mport-root. A malicious or malformed package manifest could therefore direct privileged...

CVE-2026-54580

mport is the MidnightBSD Package Manager. Prior to 2.7.8, libmport/util.c did not make every truncated, corrupt, or failed zstd stream fatal in mportdecompresszstd, and libmport/fetch.c did not consistently propagate those failures to index-fetch callers. A malicious or faulty mirror could supply...
