[GLSA-200504-01] telnet-bsd: Multiple buffer overflows Vulnerability Scan
Vulnerability Scan Summary
telnet-bsd: Multiple buffer overflows
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200504-01
(telnet-bsd: Multiple buffer overflows)
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.
Impact
Successful exploitation would require a vulnerable user to connect
to a possible hacker-controlled host using telnet, potentially executing
arbitrary code with the permissions of the telnet user.
Workaround
There is no known workaround at this time.
