Insight
Insight
The telnet(1) command is a TELNET protocol client, used primarily to establish terminal sessions across a network. Buffer overflows were discovered in the env_opt_add() and slc_add_reply() functions of the telnet(1) command. TELNET protocol commands, options, and data are copied from the network to a fixed-sized buffer. In the case of env_opt_add (CVE-2005-0468), the buffer is located on the heap. In the case of slc_add_reply (CVE-2005-0469), the buffer is global uninitialized data (BSS).
