Doc Text:
A flaw was found in the libxslt library. The same memory field, psvi, is used for both stylesheet and input data, which can lead to type confusion during XML transformations. This vulnerability allows an attacker to crash the application or corrupt memory. In some cases, it may lead to denial of service or unexpected behavior.

Description OSIDB Bzimport 2025-07-10 08:56:25 UTC
Type confusion in xmlNode.psvi between stylesheet and source nodes of libxslt. Due to sharing of the psvi field, data from the style-sheet context may be misinterpreted when used for source document nodes during XSLT transformations. As a result, parsing a crafted XSLT can corrupt memory or crash the application, and may allow remote code execution without authentication or user interaction, disrupting services that rely on libxslt.
