CVE-2023-0216
Public on 2023-02-08
Modified on 2024-02-03
Description
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.
