Package : inetutils
Version : 2:1.9.4-7+deb10u2
CVE ID : CVE-2019-0053 CVE-2021-40491 CVE-2022-39028
Debian Bug : 945861 956084 993476
Several security vulnerabilities were discovered in inetutils, a
collection of common network programs.
CVE-2019-0053
inetutils' telnet client doesn't sufficiently validate environment
variables, which can lead to stack-based buffer overflows. This
issue is limited to local exploitation from restricted shells.
CVE-2021-40491
inetutils' ftp client before 2.2 does not validate addresses
returned by PSV/LSPV responses to make sure they match the server
address. A malicious server can exploit this flaw to reach services
in the client's private network. (This is similar to curl's
CVE-2020-8284.)
CVE-2022-39028
inetutils's telnet server through 2.3 has a NULL pointer dereference
which a client can trigger by sending 0xff 0xf7 or 0xff 0xf8. In a
typical installation, the telnetd application would crash but the
telnet service would remain available through inetd. However, if the
telnetd application has many crashes within a short time interval,
the telnet service would become unavailable after inetd logs a
"telnet/tcp server failing (looping), service terminated" error.
For Debian 10 buster, these problems have been fixed in version
2:1.9.4-7+deb10u2.
We recommend that you upgrade your inetutils packages.
