Description

This security bulletin contains information about 2 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2024-24791)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of "Expect: 100-continue" HTTP requests. A remote attacker can send multiple such requests and consume all available resources.


2) 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.
