[GLSA-200410-03] NetKit-telnetd: buffer overflows in telnet and telnetd |

NetKit-telnetd: buffer overflows in telnet and telnetd Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200410-03 (NetKit-telnetd: buffer overflows in telnet and telnetd) A possible buffer overflow exists in the parsing of option strings by the telnet daemon, where proper bounds checking is not applied when writing to a buffer. Additionaly, another possible buffer overflow has been found by Josh Martin in the handling of the environment variable HOME. Impact A remote attacker sending a specially-crafted options string to the telnet daemon could be able to run arbitrary code with the rights of the user running the telnet daemon, usually root. Furthermore, a possible hacker could make use of an overlong HOME variable to cause a buffer overflow in the telnet client, potentially leading to the local execution of arbitrary code. Workaround There is no known workaround at this time.
