CWE-682  (opens in a new tab)

How to fix?

Upgrade RHEL:7 openssh-askpass to version 0:6.6.1p1-23.el7_2 or higher.
This issue was patched in RHSA-2016:0043.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-askpass package and not the openssh-askpass package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
