CVE-2017-7523

Name of the Vulnerable Software and Affected Versions Cygwin versions 1.7.2 through 1.8.0

Description The issue is related to a buffer overflow vulnerability in the wcsxfrm and wcsxfrm l functions. This can result in a denial-of-service by crashing the process or potentially allow hijacking of the process running with administrative privileges. The vulnerability can be triggered by a specially crafted input string.

Recommendations For Cygwin versions 1.7.2 through 1.8.0, consider updating to a version that includes a fix for the buffer overflow vulnerability in the wcsxfrm and wcsxfrm l functions. As a temporary workaround, restrict the use of these functions to minimize the risk of exploitation.
