Package : amanda
Version : 1:3.5.1-2+deb10u2
CVE ID : CVE-2022-37703 CVE-2022-37705 CVE-2023-30577
Debian Bug : 1021017 1029829 1055253
Multiple vulnerabilties have been found in Amanda,a backup system
designed to archive many computers on a network to a single
large-capacity tape drive. The vulnerabilties potentially allows local
privilege escalation from the backup user to root or leak information
whether a directory exists in the filesystem.
CVE-2022-37703
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.
CVE-2022-37705
A privilege escalation flaw was found in Amanda 3.5.1 in which the
backup user can acquire root privileges. The vulnerable component is
the runtar SUID program, which is a wrapper to run /usr/bin/tar with
specific arguments that are controllable by the attacker. This
program mishandles the arguments passed to tar binary.
CVE-2023-30577
The SUID binary "runtar" can accept the possibly malicious GNU tar
options if fed with some non-argument option starting with
"--exclude" (say --exclude-vcs). The following option will be
accepted as "good" and it could be an option passing some
script/binary that would be executed with root permissions.
For Debian 10 buster, these problems have been fixed in version
1:3.5.1-2+deb10u2.
We recommend that you upgrade your amanda packages.
