Name of the Vulnerable Software and Affected Versions:
Pengutronix barebox versions through 2021.07.0
Description:
The issue is related to the
crypto/digest.c file in Pengutronix barebox, where the use of memcmp during digest verification leaks timing information.Recommendations:
For versions through 2021.07.0, consider updating to a version later than 2021.07.0 to resolve the issue.
As a temporary workaround, consider modifying the
crypto/digest.c file to use a constant-time comparison function instead of memcmp until a patch is available. وجدت خطأً في الوصف؟ لديك ما تضيفه؟ لا تتردد في مراسلتنا 👾
