Off-by-one error in the __opiereadrec function in readrec.c in libopie in OPIE 2.4.1-test1 and earlier, as used on FreeBSD 6.4 through 8.1-PRERELEASE and other platforms, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long username, as demonstrated by a long USER command to the FreeBSD 8.0 ftpd.

Security readout for executives and security teams

This is an old memory-safety flaw in OPIE authentication code. A remote user could send an overly long username to a service using libopie and crash the daemon, with possible arbitrary code execution noted but not proven in the bundle. Exposure is most likely on legacy Unix/BSD systems using OPIE/libopie for authentication, especially FTP daemons or other network services linked to libopie. Modern environments are unlikely to be affected unless they still run old OPIE packages. Treat as a legacy exposure cleanup issue unless affected internet-facing services are found. Prioritize patching or removing OPIE on old FreeBSD/Debian systems and any externally reachable FTP authentication paths. Mitigation focus: Identify systems running OPIE 2.4.1-test1 or earlier.; Review FreeBSD-SA-10:05 and Debian DSA-2281 for vendor-specific fixes.; Apply vendor-supported updates or backported security patches..
