Description
This security bulletin contains information about 1 vulnerability.
1) Use of Uninitialized Variable (CVE-ID: CVE-2024-9355)
CWE-ID: CWE-457 - Use of Uninitialized Variable
CVSSv4: 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
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.
