CVE-2015-8983

Name of the Vulnerable Software and Affected Versions GNU C Library (aka glibc or libc6) versions prior to 2.22

Description The issue is related to an integer overflow in the IO wstr overflow function, which can lead to a denial of service (application crash) or possibly allow execution of arbitrary code. This is triggered by computing a size in bytes, resulting in a heap-based buffer overflow.

Recommendations For versions prior to 2.22, update to version 2.22 or later to resolve the issue. As a temporary workaround, consider restricting the use of the IO wstr overflow function to minimize the risk of exploitation.
