HighMetricsAV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
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.Exploitability
