Security readout for executives and security teams
A very old bug in the Linux "dump" package's restore program lets a local user on the same machine trick the software into running commands it should not, by supplying an overly long tape name. It affects restore version 0.4b17 and earlier and requires the attacker to already have a login on the system. Exposure today is minimal. The flaw applies only to Linux systems still running dump/restore 0.4b17 or earlier from around 2000. Modern distributions have long since patched or removed the affected code. Any residual exposure would be on unmaintained legacy Unix hosts where the vulnerable binary remains installed and accessible to local users. Very low priority. This is a 25-year-old local privilege bug in a Linux backup utility that has been patched by every mainstream distribution. Address it only if legacy systems remain in scope for a compliance audit or asset review. Mitigation focus: Upgrade the dump package to a version later than 0.4b17 using current distribution repositories.; Remove the setuid bit from restore if it is not required for operations.; Restrict local shell access on hosts running legacy backup utilities..
