Other products, platforms, and configurations are not affected by this vulnerability. The jbuf memory leak only occurs in SSL Proxy and UTM Web-Filtering configurations. Service restoration is only possible by rebooting the system. Certifi 2023.07.22 removes root certificates from "e-Tugra" from the root store.Īn Improper Check or Handling of Exceptional Conditions vulnerability in the UTM (Unified Threat Management) Web-Filtering feature of Juniper Networks Junos OS on SRX Series causes a jbuf memory leak to occur when accessing certain websites, eventually leading to a Denial of Service (DoS) condition. e-Tugra's root certificates were subject to an investigation prompted by reporting of security issues in their systems. Certifi prior to version 2023.07.22 recognizes "e-Tugra" root certificates. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.Ĭertifi is a curated collection of Root Certificates for validating the trustworthiness of SSL certificates while verifying the identity of TLS hosts. The OpenSSL SSL/TLS implementation is not affected by this issue. Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the "-check" option. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check(). ![]() An application calling any of those other functions may similarly be affected. The function DH_check() is itself called by a number of other OpenSSL functions. 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. 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. ![]() 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. The function DH_check() performs various checks on DH parameters. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. 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. Issue summary: Checking excessively long DH keys or parameters may be very slow. ![]() This flaw allows an attacker to exhaust all available connections. Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections.
