Ncsa : Security Vulnerabilities, CVEs, (Overflow)

Buffer overflow in the slc_add_reply function in various BSD-based Telnet clients, when handling LINEMODE suboptions, allows remote attackers to execute arbitrary code via a reply with a large number of Set Local Character (SLC) commands.

Heap-based buffer overflow in the env_opt_add function in telnet.c for various BSD-based Telnet clients allows remote attackers to execute arbitrary code via responses that contain a large number of characters that require escaping, which consumers more memory than allocated.

Buffer overflow in NCSA HTTP daemon v1.3 allows remote command execution.

Buffer overflow in NCSA WebServer (1.4.1 and below) gives remote access.
