Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in OpenSSL. An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. This may result in an application crash which could lead to a denial of service. The TLS implementation in OpenSSL does not call this function, however, third party applications might call these functions on untrusted data.

Description Marian Rehak 2023-01-25 15:45:41 UTC 
An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in OpenSSL does not call this function however third party applications might call these functions on untrusted data.
