A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases when using int("text") a system could take 50ms to parse an int string with 100000 digits and 5s for 1000000 digits (float decimal int.from_bytes() and int() for binary bases 2 4 8 16 and 32 are not affected). The highest threat from this vulnerability is to system availability.

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.
