Description
This security bulletin contains information about 3 vulnerabilities.
1) Missing Release of Resource after Effective Lifetime (CVE-ID: CVE-2024-2398)
CWE-ID: CWE-772 - Missing Release of Resource after Effective Lifetime
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/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 an error when sending HTTP/2 server push responses with an overly large number of headers. A remote attacker can send PUSH_PROMISE frames with an excessive amount of headers to the application, trigger memory leak and perform a denial of service (DoS) attack.
2) Improper validation of certificate with host mismatch (CVE-ID: CVE-2024-2466)
CWE-ID: CWE-297 - Improper Validation of Certificate with Host Mismatch
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to libcurl does not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. A remote attacker force the application to completely skip the certificate check and perform MitM attack.
3) Input validation error (CVE-ID: CVE-2024-2004)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to an error when a protocol selection parameter option disables all protocols without adding any. As a result, the default set of protocols would remain in the allowed set due to an error in the logic for removing protocols.
