+Subject: [PATCH] Properly verify adbe.pkcs7.sha1 signatures.
+
+For signatures with non-empty encapsulated content
+(typically adbe.pkcs7.sha1), we only compared hash values and
+never actually checked SignatureValue within SignerInfo.
+The bug introduced by c7c0207b
+made trivial signature forgeries possible. Fix this by calling
+NSS_CMSSignerInfo_Verify() after the hash values compare equal.
+
+CVE: CVE-2025-43903
+Upstream-Status: Backport [https://gitlab.freedesktop.org/poppler/poppler/-/commit/f1b9c830f145a0042e853d6462b2f9ca4016c669]
