Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.57 SP2 security update
Notes
Topic
Red Hat JBoss Core Services Apache HTTP Server 2.4.57 Service Pack 2 is now available.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This software, such as Apache HTTP Server, is common to multiple JBoss middleware products and packaged under Red Hat JBoss Core Services, to allow for faster distribution of updates and for a more consistent update experience.
This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.57 Service Pack 2 serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.57 Service Pack 1, and includes bug fixes and enhancements, which are documented in the Release Notes linked to in the References section.
Security Fix(es):
* curl: a heap based buffer overflow in the SOCKS5 proxy handshake (CVE-2023-38545)
* curl: out of heap memory issue due to missing limit on header quantity (CVE-2023-38039)
* curl: cookie injection with none file (CVE-2023-38546)
* jbcs-httpd24-mod_jk: httpd: Apache Tomcat Connectors (mod_jk) Information Disclosure (CVE-2023-41081)
* jbcs-httpd24-openssl: OpenSSL: Excessive time spent checking DH q parameter value (CVE-2023-3817)
* libxml2: crafted xml can cause global buffer overflow (CVE-2023-39615)
* mod_http2: reset requests exhaust memory (incomplete fix of CVE-2023-44487) (CVE-2023-45802)
* openssl: Excessive time spent checking DH keys and parameters (CVE-2023-3446)
* openssl: Invalid certificate policies in leaf certificates are silently ignored (CVE-2023-0465)
* openssl: Possible DoS translating ASN.1 object identifiers (CVE-2023-2650)
* openssl: Denial of service by excessive resource usage in verifying X509 policy constraints (CVE-2023-0464)
* openssl: Certificate policy check not enabled (CVE-2023-0466)
* zlib: integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_6 (CVE-2023-45853)
A Red Hat Security Bulletin which addresses further details about this flaw is available in the References section.

Suddenly enabling the policy check could break existing deployments, so it was decided to keep the existing behavior of the X509_VERIFY_PARAM_add0_policy() function. The applications that require OpenSSL to perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument.

Firstly, while the potential for a Denial of Service (DoS) attack exists, it requires specific conditions to be met, notably the use of DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions with DH keys or parameters obtained from untrusted sources. Secondly, the issue primarily affects the efficiency of key and parameter checks, rather than directly compromising the security or integrity of cryptographic operations.

However, the maximum length of the hostname that can be passed is 255 bytes. If the hostname is longer, then Curl switches to the local name resolving and passes the resolved address only to the proxy. The local variable that instructs Curl to \"let the host resolve the name\" could obtain the wrong value during a slow SOCKS5 handshake, resulting in the too-long hostname being copied to the target buffer instead of the resolved address, which was not the intended behavior.",
