# `NULL` dereference during PKCS7 data verification | ||
|
||
A `NULL` pointer can be dereferenced when signatures are being | ||
verified on PKCS7 `signed` or `signedAndEnveloped` data. In case the hash | ||
algorithm used for the signature is known to the OpenSSL library but | ||
the implementation of the hash algorithm is not available the digest | ||
initialization will fail. There is a missing check for the return | ||
value from the initialization function which later leads to invalid | ||
usage of the digest API most likely leading to a crash. | ||
|
||
The unavailability of an algorithm can be caused by using FIPS | ||
enabled configuration of providers or more commonly by not loading | ||
the legacy provider. | ||
|
||
PKCS7 data is processed by the SMIME library calls and also by the | ||
time stamp (TS) library calls. The TLS implementation in OpenSSL does | ||
not call these functions however third party applications would be | ||
affected if they call these functions to verify signatures on untrusted | ||
data. |
