Original advisory details:

Maher Azzouzi discovered an information disclosure vulnerability in the
calcsize binary within amanda. calcsize is a suid binary owned by root that
could possibly be used by a malicious local attacker to expose sensitive
file system information. (CVE-2022-37703)

Maher Azzouzi discovered a privilege escalation vulnerability in the
rundump binary within amanda. rundump is a suid binary owned by root that
did not perform adequate sanitization of environment variables or
commandline options and could possibly be used by a malicious local
attacker to escalate privileges. (CVE-2022-37704)

Maher Azzouzi discovered a privilege escalation vulnerability in the runtar
binary within amanda. runtar is a suid binary owned by root that did not
perform adequate sanitization of commandline options and could possibly be
used by a malicious local attacker to escalate privileges. (CVE-2022-37705)");
