Description
The issue is related to the implementation of ASN1 TFLG COMBINE in the OpenSSL library, specifically in the crypto/asn1/tasn dec.c file. It is associated with a lack of protection for service data. Exploitation of this issue may allow a remote attacker to obtain sensitive information from the process memory. This can occur by triggering a decoding failure in a PKCS#7 or CMS application using malformed X509 ATTRIBUTE data.
