CVE-2021-30004
Description
A flaw was found in wpa_supplicant, in the way it handled digest algorithm parameters when validating a signature. This flaw could be exploited to perform potential forging attacks. The highest threat from this vulnerability is to data integrity.
Statement
This issue only affects the "internal" TLS implementation. The versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 6, 7, and 8 are not affected by this flaw, as they use the OpenSSL implementation by default. More specifically, the CONFIG_TLS=internal flag is not set at compile time.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
