GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.
