Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.51 SP2 security update
Notes
Topic
Red Hat JBoss Core Services Apache HTTP Server 2.4.51 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 is 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 2.4.51 Service Pack 2 serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.51 Service Pack 1, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
Security Fix(es):
* apr-util: out-of-bounds writes in the apr_base64 (CVE-2022-25147)
* expat: use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate (CVE-2022-43680)
* curl: HSTS bypass via IDN (CVE-2022-43551)

* curl: HTTP multi-header compression denial of service (CVE-2023-23916)
* curl: TELNET option IAC injection (CVE-2023-27533)
* curl: SFTP path ~ resolving discrepancy (CVE-2023-27534)
* expat: use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate (CVE-2022-43680)
* httpd: mod_dav: out-of-bounds read/write of zero byte (CVE-2006-20001)
* httpd: HTTP request splitting with mod_rewrite and mod_proxy (CVE-2023-25690)
* openssl: timing attack in RSA Decryption implementation (CVE-2022-4304)
* openssl: double free after calling PEM_read_bio_ex (CVE-2022-4450)
* openssl: use-after-free following BIO_new_NDEF (CVE-2023-0215)
* openssl: X.400 address type confusion in X.509 GeneralName (CVE-2023-0286)

The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the \"name\" (for example, \"CERTIFICATE\"), any header data, and the payload data. If the function succeeds, then the \"name_out,\" \"header,\" and \"data\" arguments are populated with pointers to buffers containing the relevant decoded data. The caller is responsible for freeing those buffers. Constructing a PEM file that results in 0 bytes of payload data is possible. In this case, PEM_read_bio_ex() will return a failure code but will populate the header argument with a pointer to a freed buffer. A double-free will occur if the caller also frees this buffer. This will most likely lead to a crash. This could be exploited by an attacker who can supply malicious PEM files for parsing to achieve a denial of service attack.",

Using its HSTS support, curl can be instructed to use HTTPS instead of an insecure clear-text HTTP step even when providing HTTP in the URL. Suppose the hostname in the given URL first uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion. In that case, it can bypass the HSTS mechanism using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop (U+002E).

It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be called directly by end-user applications. The function receives a BIO from the caller, prepends a new BIO_f_asn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the BIO chain to the caller. Under certain conditions. For example, if a CMS recipient public key is invalid, the new filter BIO is freed, and the function returns a NULL result indicating a failure. However, in this case, the BIO chain is not properly cleaned up, and the BIO passed by the caller still retains internal pointers to the previously freed filter BIO. If the caller then calls BIO_pop() on the BIO, a use-after-free will occur, possibly resulting in a crash.",

In most cases, the attack requires the attacker to provide both the certificate chain and CRL, of which neither needs a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon.
