Security update for openssh-openssl1

This update for openssh-openssl1 fixes the following issues:

  • CVE-2016-0777: A malicious or compromised server could cause the OpenSSH client to expose part or all of the client's private key through the roaming feature (bsc#961642)
  • CVE-2016-0778: A malicious or compromised server could could trigger a buffer overflow in the OpenSSH client through the roaming feature (bsc#961645)

This update disables the undocumented feature supported by the OpenSSH client and a commercial SSH server.

Описание

The resend_bytes function in roaming_common.c in the client in OpenSSH 5.x, 6.x, and 7.x before 7.1p2 allows remote servers to obtain sensitive information from process memory by requesting transmission of an entire buffer, as demonstrated by reading a private key.

Описание

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) or possibly have unspecified other impact by requesting many forwardings.
