There is an old path traversal issue that we've not fixed. The text of the message describing this: The tar patch "tar-1.13.25-dots.patch" changes.... for (;;) { if (p[0] == '.' && p[1] == '.' && (ISSLASH (p[2]) || !p[2])) return 1; do { if (! *p++) return 0; } while (! ISSLASH (*p)); } ...into... for (;;) { if (p[0] == '.' && p[1] == '.' && (ISSLASH (p[2]) || !p[2])) return 1; do { if (! *p++) return 0; } while (! ISSLASH (*p)); do { if (! *p++) return 0; } while ( ISSLASH (*p)); } ...which looks like it's an optimization, however it also changes the answer for "/../etc/passwd" ... changing both do while's to just plain while's should fix it. This issue also affects RHEL 2.1
