CVE-2025-24056 [HIGH] CWE-122 Windows Telephony Service Remote Code Execution Vulnerability
Windows Telephony Service Remote Code Execution Vulnerability
Description: Heap-based buffer overflow in Windows Telephony Server allows an unauthorized attacker to execute code over a network.
FAQ: According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?
This attack requires a client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.
FAQ: How could an attacker exploit this vulnerability?
An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

In pkgconf through 1.9.3 variable duplication can cause unbounded string expansion due to incorrect checks in libpkgconf/tuple.c:pkgconf_tuple_parse. For example a .pc file containing a few hundred bytes can expand to one billion bytes.
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 produc
