CVE-2022-25313 [MEDIUM] CWE-776 expat: Stack exhaustion in doctype parsing
expat: Stack exhaustion in doctype parsing
In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element.
A flaw was found in expat. A stack exhaustion in doctype parsing could be triggered by a file with a large number of opening braces, resulting in a denial of service.
Statement: This flaw affects applications that leverage expat to parse untrusted XML files. Applications which only parse trusted XML files or do not process XML files at all are not affected by this flaw.
Mitigation: There is no known mitigation other than restricting applications using the expat library from processing untrusted XML content.
Package: expat (Red Hat Enterprise Linux 6) - Out of support scope

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
