Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for openssl (EulerOS-SA-2023-3382)
Summary:	The remote host is missing an update for the Huawei EulerOS 'openssl' package(s) announced via the EulerOS-SA-2023-3382 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'openssl' package(s) announced via the EulerOS-SA-2023-3382 advisory. Vulnerability Insight: Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs various checks on DH parameters. After fixing CVE-2023-3446 it was discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A correct q value, if present, cannot be larger than the modulus p parameter, thus it is unnecessary to perform these checks if q is larger than p. An application that calls DH_check() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check(). Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the '-check' option. The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.(CVE-2023-3817) Affected Software/OS: 'openssl' package(s) on Huawei EulerOS Virtualization release 2.11.0. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
