Description

This update for osslsigncode fixes the following issues: Changes in osslsigncode: - Update to 2.13 (bsc#1260680, CVE-2025-70888): * fixed integer overflows when processing APPX compressed data streams * fixed double-free vulnerabilities in APPX file processing * fixed multiple memory corruption issues in PE page hash computation - Changes from 2.12: * fixed a buffer overflow while extracting message digests - Changes from 2.11: * added keyUsage validation for signer certificate * added printing CRL details during signature verification * implemented a workaround for CRL servers returning the HTTP Content-Type header other than application/pkix-crl * fixed HTTP keep-alive handling * fixed macOS compiler and linker flags * fixed undefined BIO_get_fp() behavior with BIO_FLAGS_UPLINK_INTERNAL - update to 2.10: * added JavaScript signing * added PKCS#11 provider support (requires OpenSSL 3.0+) * added support for providers without specifying "-pkcs11module" option * (OpenSSL 3.0+, e.g., for the upcoming CNG provider) * added compatibility with the CNG engine version 1.1 or later * added the "-engineCtrl" option to control hardware and CNG engines * added the '-blobFile' option to specify a file containing the blob content * improved unauthenticated blob support (thanks to Asger Hautop Drewsen) * improved UTF-8 handling for certificate subjects and issuers * fixed support for multiple signerInfo contentType OIDs (CTL and Authenticode) * fixed tests for python-cryptography >= 43.0.0 - update to version 2.9: * added a 64 bit long pseudo-random NONCE in the TSA request * missing NID_pkcs9_signingTime is no longer an error * added support for PEM-encoded CRLs * fixed the APPX central directory sorting order * added a special "-" file name to read the passphrase from stdin * used native HTTP client with OpenSSL 3.x, removing libcurl dependency * added '-login' option to force a login to PKCS11 engines * added the "-ignore-crl" option to disable fetching and verifying CRL Distribution Points * changed error output to stderr instead of stdout * various testing framework improvements * various memory corruption fixes - update to version 2.8: * Microsoft PowerShell signing sponsored by Cisco Systems, Inc. * fixed setting unauthenticated attributes (Countersignature, Unauthenticated * Data Blob) in a nested signature * added the "-index" option to verify a specific signature or modify its unauthenticated attributes * added CAT file verification * added listing the contents of a CAT file with the "-verbose" option * added the new "extract-data" command to extract a PKCS#7 data content to be signed with "sign" and attached with "attach-signature" * added PKCS9_SEQUENCE_NUMBER authenticated attribute support * added the "-ignore-cdp" option to disable CRL Distribution Points (CDP) online verification * unsuccessful CRL retrieval and verification changed into a critical error the "-p" option modified to also use to configured proxy to connect CRL Distribution Points * added implicit allowlisting of the Microsoft Root Authority serial number 00C1008B3C3C8811D13EF663ECDF40 * added listing of certificate chain retrieved from the signature in case of verification failure
