RHBA-2012:1035 - telnet bug fix update

Synopsis

telnet bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated telnet packages that fix four bugs are now available for Red Hat Enterprise Linux 5.

Description

Telnet is a popular protocol for logging in to remote systems over the Internet. The telnet service is disabled by default.

This update fixes following bugs:

  • Prior to this update, the telnet.spec file used the "%{dist}" macro instead of the "%{?dist}", which violated packaging guidelines. This update replaces the macro with the correct one. (BZ#440614)

  • Prior to this update, the telnet utility used the sockaddr structure as storage for IPv6 addresses. As a consequence, telnet could emit incomplete IPv6 addresses because the sockaddr structure is to small to hold an IPv6 address. This update modifies telnet to use the sockaddr_storage structure as IPv6 address storage and now emits complete IPv6 addresses. (BZ#678336)

  • Prior to this update, the telnet utility could enter an infinite loop when the user specified the "-b" parameter with a non-existing network interface. This update modifies the telnet command to print errors when users specify a non-existing network interface. (BZ#772860)

  • Prior to this update, the in.telnetd daemon could fail to update information in the /var/run/utmp directory when a deadlock occured in a telnet session. This update modifies telnetd to update /var/run/utmp correctly. (BZ#825946)

All users of telnet are advised to upgrade to these updated packages, which fix these bugs.

Solution
