OpenSSH Information Maintain Connection File Descriptors Vulnerabilities
22 Apr. 2016
Summary
The (1) roaming_read and (2) roaming_write functions in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2, when certain proxy and forward options are enabled, do not properly maintain connection file descriptors, which allows remote servers to cause a denial of service (heap-based buffer overflow).
Vulnerable Systems:
*OpenSSH 5.x, 6.x, and 7.x before 7.1p2
Immune Systems:
*OpenSSH 5.x, 6.x, and 7.x after 7.1p2
OpenSSH is prone to an information-disclosure vulnerability. Successfully exploiting this issue allows attackers to obtain sensitive information that may aid in further attacks.
