Title:	Huawei EulerOS: Security Advisory for telnet (EulerOS-SA-2024-1975)
Summary:	The remote host is missing an update for the Huawei EulerOS 'telnet' package(s) announced via the EulerOS-SA-2024-1975 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'telnet' package(s) announced via the EulerOS-SA-2024-1975 advisory. Vulnerability Insight: 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-appl is not supported upstream but is shipped by a few Linux distributions. The affected code was removed from the supported MIT Kerberos 5 (aka krb5) product many years ago, at version 1.8.(CVE-2022-39028) Affected Software/OS: 'telnet' package(s) on Huawei EulerOS V2.0SP9(x86_64). Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
