| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2026-32772 | telnet in GNU inetutils through 2.7 allows servers to read arbitrary environment variables from clients via NEW_ENVIRON SEND USERVAR. | [email protected] | 3.4 | 0.19% | 2026-03-16 | 2026-06-17 |
| CVE-2026-32746 | telnetd in GNU inetutils through 2.7 allows an out-of-bounds write in the LINEMODE SLC (Set Local Characters) suboption handler because add_slc does not check whether the buffer is full. | [email protected] | 9.8 | 23.67% | 2026-03-13 | 2026-06-17 |
| CVE-2026-28372 | telnetd in GNU inetutils through 2.7 allows privilege escalation that can be exploited by abusing systemd service credentials support added to the login(1) implementation of util-linux in release 2.40. This is related to client control over the CREDENTIALS_DIRECTORY environment variable, and requires an unprivileged local user to create a login.noauth file. | [email protected] | 7.4 | 0.37% | 2026-02-27 | 2026-06-17 |
| CVE-2026-24061 KEV | telnetd in GNU Inetutils through 2.7 allows remote authentication bypass via a "-f root" value for the USER environment variable. | [email protected] | 9.8 | 98.87% | 2026-01-21 | 2026-06-17 |
| CVE-2023-40303 | GNU inetutils before 2.5 may allow privilege escalation because of unchecked return values of set*id() family functions in ftpd, rcp, rlogin, rsh, rshd, and uucpd. This is, for example, relevant if the setuid system call fails when a process is trying to drop privileges before letting an ordinary user control the activities of the process. | [email protected] | 7.8 | 0.39% | 2023-08-14 | 2026-06-17 |
| CVE-2022-39028 | telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 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. NOTE: MIT krb5-app | [email protected] | 7.5 | 1.60% | 2022-08-30 | 2026-06-17 |
| CVE-2021-40491 | The ftp client in GNU Inetutils before 2.2 does not validate addresses returned by PASV/LSPV responses to make sure they match the server address. This is similar to CVE-2020-8284 for curl. | [email protected] | 6.5 | 0.93% | 2021-09-02 | 2026-06-17 |
| CVE-2011-4862 | Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011. | [email protected] | 10.0 | 95.10% | 2011-12-24 | 2026-06-16 |
