a/tar-1.34-x86_64-3.txz: Rebuilt.
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.
Thanks to marav for the heads-up.
