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.

The version of libxslt installed on the remote host is prior to 1.1.28-6. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2966 advisory.

    Two vunlerabilities were found in libxslt, the XSLT 1.0 processing library,     which may lead to information disclosure and DoS attack.

    CVE-2023-40403

        Information disclosure with weak memory handling of generated-id()

    CVE-2025-7424

        Type confusion in xmlNode.psvi between stylesheet and source nodes,         which may allow an attacker to crash the application or corrupt memory.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 1.1.35-1+deb12u2.

    For the stable distribution (trixie), these problems have been fixed in     version 1.1.35-1.2+deb13u1.

    We recommend that you upgrade your libxslt packages.

The remote host is running a version of macOS / Mac OS X that is 15.x prior to 15.6. It is, therefore, affected by multiple vulnerabilities:

  - 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. (CVE-2025-7424)

  - Insufficient validation of untrusted input in ANGLE and GPU in Google Chrome prior to 138.0.7204.157     allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium     security severity: High) (CVE-2025-6558)

  - A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts     internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this     corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory,     causing crashes or enabling attackers to trigger heap corruption. (CVE-2025-7425)
