EUVDB-ID: #VU98022

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-9355

CWE-ID: CWE-457 - Use of Uninitialized Variable

Exploit availability: No

Description

The vulnerability allows a remote attacker to weaken TLS encryption.

The vulnerability exists due to an uninitialized buffer length variable in the CGO bindings that intermittently return a zeroed buffer from (*boringHMAC).Sum() in FIPS mode. A remote attacker can randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode and weaken TLS security.

Mitigation

Install updates from vendor's repository.
