Multiple buffer overflows in Advanced Maryland Automatic Network Disk Archiver (AMANDA) 2.3.0.4 allow (1) remote attackers to execute arbitrary code via long commands to the amindexd daemon, or certain local users to execute arbitrary code via long command line arguments to the programs (2) amcheck, (3) amgetidx, (4) amtrmidx, (5) createindex-dump, or (6) createindex-gnutar.

In Amanda 3.5.1, an information leak vulnerability was found in the calcsize SUID binary. An attacker can abuse this vulnerability to know if a directory exists or not anywhere in the fs. The binary will use `opendir()` as root directly without checking the path, letting the attacker provide an arbitrary path.
