+ telnet-bsd provides a command line telnet client which is used for + remote login using the telnet protocol. +

+
+ +

+ A buffer overflow has been identified in the env_opt_add() + function of telnet-bsd, where a response requiring excessive escaping + can cause a heap-based buffer overflow. Another issue has been + identified in the slc_add_reply() function, where a large number of SLC + commands can overflow a fixed size buffer. +

+
+ +

+ Successful exploitation would require a vulnerable user to connect + to an attacker-controlled host using telnet, potentially executing + arbitrary code with the permissions of the telnet user. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All telnet-bsd users should upgrade to the latest version: +

+ + # emerge --sync + # emerge --ask --oneshot --verbose ">=net-misc/telnet-bsd-1.0-r1" +
