CVE-2025-32050 [HIGH] libsoup vulnerabilities
Title: libsoup vulnerabilities
Summary: Several security issues were fixed in libsoup.
It was discovered that libsoup could be made to read out of bounds. An
attacker could possibly use this issue to cause applications using
libsoup to crash, resulting in a denial of service. (CVE-2025-2784,
CVE-2025-32050, CVE-2025-32052, CVE-2025-32053)
It was discovered that libsoup could be made to dereference invalid
memory. An attacker could possibly use this issue to cause applications
using libsoup to crash, resulting in a denial of service.
(CVE-2025-32051)
Instructions: In general, a standard system update will make all the necessary changes.

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.
