NIST CVE Summary
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.
CVE Severity
Our Official Summary
A NULL pointer vulnerability was found in OpenSSL, which can be dereferenced when signatures are being verified on PKCS7 signed or signedAndEnveloped data. 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 images where this vulnrability is have controls in place are not accessible outside the cluster. So the attacker needs to gain privileged access to the cluster to attempt this exploit. Also the containers do not allow execution of arbitrary code. Impact of this exploit is also low, since container reduces the attack surface.
