CVE-2026-54585: Improper Limitation of a Pathname to a Restricted Directory

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-2026-54582: External Control of File Name or Path

mport is the MidnightBSD Package Manager. Prior to 2.7.8, package installation lacked a preflight check for incoming non-directory assets that already existed on disk. The affected logic across libmport/checkpreconditions.c, libmport/installprimative.c, and libmport/mportprivate.h did not apply...

CVE-2026-54586: Cleartext Transmission of Sensitive Information

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-2026-54583: Improper Limitation of a Pathname to a Restricted Directory

mport is the MidnightBSD Package Manager. Prior to 2.7.8, libmport/fetch.c did not consistently reject empty, dot, dot-dot, or slash-containing bundle filenames before composing package download and write paths. Malicious package index data could place an unsafe value in indexEntry-bundlefile, an...

CVE-2026-54587: Improper Link Resolution Before File Access

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-2026-54576: Improper Link Resolution Before File Access

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-2026-54580: Improper Validation of Integrity Check Value

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...

CVE-2026-54579: Out-of-bounds Read

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-2026-54575: Improper Neutralization of Special Elements used in an OS Command

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-2020-24385

In MidnightBSD before 1.2.6 and 1.3 before August 2020, and FreeBSD before 7, a NULL pointer dereference was found in the Linux emulation layer that allows attackers to crash the running kernel. During binary interaction, td-tdemuldata in sys/compat/linux/linuxemul.h is not getting initialized an...
