RHBA-2011:0963 - telnet bug fix update
Synopsis
telnet bug fix update
Type/Severity
Bug Fix Advisory (none)
Topic
Updated telnet packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Description
Telnet is a popular protocol for logging in to remote systems over the Internet. The telnet-server package includes a telnet service that supports remote logins into the host machine. The telnet service is disabled by default.
This update fixes the following bug:
- Prior to this update, the in.telnetd service used the sockaddr structure to store IPv6 addresses. This structure was too small in its size, and as a result, subsequent logins wrote incorrect records about the last login source. With this update, in.telnetd now uses the sockaddr_storage structure, which is large enough in its size to be able to store IPv6 addresses. (BZ#678324)
All users of telnet are advised to upgrade to these updated packages, which fix this bug.
Solution
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
