Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.51 security update
Notes
Topic
An update is now available for Red Hat JBoss Core Services.
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 serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.37 Service Pack 10, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.
Security Fix(es):
* zlib: A flaw found in zlib when compressing (not decompressing) certain inputs (CVE-2018-25032)
* expat: Malformed 2- and 3-byte UTF-8 sequences can lead to arbitrary code execution (CVE-2022-25235)
* expat: Namespace-separator characters in "xmlns[:prefix]" attribute values can lead to arbitrary code execution (CVE-2022-25236)
* expat: Integer overflow in storeRawNames() (CVE-2022-25315)

* httpd: Out-of-bounds write in ap_escape_quotes() via malicious input (CVE-2021-39275)
* httpd: NULL pointer dereference via crafted request during HTTP/2 request processing (CVE-2021-41524)
* httpd: possible NULL dereference or SSRF in forward proxy configurations (CVE-2021-44224)
* expat: Large number of prefixed XML attributes on a single tag can crash libexpat (CVE-2021-45960)
* expat: Integer overflow in doProlog in xmlparse.c (CVE-2021-46143)
* expat: Integer overflow in addBinding in xmlparse.c (CVE-2022-22822)
* expat: Integer overflow in build_model in xmlparse.c (CVE-2022-22823)
* expat: Integer overflow in defineAttribute in xmlparse.c (CVE-2022-22824)
* expat: Integer overflow in lookup in xmlparse.c (CVE-2022-22825)
* expat: Integer overflow in nextScaffoldPart in xmlparse.c (CVE-2022-22826)
* expat: Integer overflow in storeAtts in xmlparse.c (CVE-2022-22827)
* expat: Integer overflow in function XML_GetBuffer (CVE-2022-23852)
* expat: stack exhaustion in doctype parsing (CVE-2022-25313)

This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",
