What is CVE-2023-52425?
CVE-2023-52425 is a high-severity vulnerability affecting the libexpat library up to version 2.5.0, which is used in various systems for XML parsing. This vulnerability allows an attacker to perform a denial of service (resource consumption) by exploiting the need for multiple full reparsings in the case of large tokens. Security updates have been released for affected software configurations, including Python versions, Debian 10 buster systems using the expat package, and Fedora 39 systems using the mingw-expat package.
Who is impacted by this?
This includes users of Python versions prior to 3.10.14, 3.9.19, and 3.8.19, Debian 10 buster systems using the expat package before version 2.2.6-2+deb10u7, and Fedora 39 systems using the mingw-expat package before version 2.6.0. The vulnerability can lead to a denial of service (resource consumption) when many full reparsings are required in the case of large tokens.
What to do if CVE-2023-52425 affected you
If you're affected by the CVE-2023-52425 vulnerability, it's crucial to update your software to mitigate the risk. Follow these steps:
For Python users, update to versions 3.10.14, 3.9.19, or 3.8.19.
Debian 10 buster users should upgrade the expat package to version 2.2.6-2+deb10u7.
Fedora 39 users need to update the mingw-expat package to version 2.6.0-1.fc39.
By updating your software, you'll help protect your system from potential denial of service attacks caused by this vulnerability.
