AZL-81192 CVE-2025-66038 affecting package opensc 0.27.1-2

OpenSC is an open source smart card tools and middleware. Prior to version 0.27.0, sccompacttlvfindtag searches a compact-TLV buffer for a given tag. In compact-TLV, a single byte encodes the tag high nibble and value length low nibble. With a 1-byte buffer 0x0A, the encoded element claims tag=0...
