Gentoo Linux Security Advisory GLSA 200504-01 – 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. Versions less than 1.0-r1 are affected.
