CVE-2022-25314 [HIGH] CWE-190 expat: Integer overflow in copyString()
expat: Integer overflow in copyString()
In Expat (aka libexpat) before 2.4.5, there is an integer overflow in copyString.
An integer overflow flaw was found in expat. This issue affects the encoding name parameter at the parser creation time, which is often hard-coded (rather than user input), takes a value in the gigabytes to trigger, and on a 64-bit machine. This flaw can cause a denial of service.
Statement: This flaw has been rated as having a severity of Moderate. The encoding name parameter is often hard-coded (rather than user input) and it would take a value in the gigabytes for the name to trigger this issue. The versions of `expat` as shipped with Red Hat Enterprise Linux 6 and 7 are not affected by this flaw as they did not include the vulnerable copyString() function.

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.
