wolfSSL.wolfssl is vulnerable to Buffer overflow (heap based)
72
High Risk
This Affects:
wolfSSL.wolfsslTL;DR
The CRL parser mishandles CRL numbers stored as hexadecimal strings and large numeric values, allowing heap-based and stack-based buffer overflows when a build has CRL support enabled and processes CRL data from an untrusted source. Crafted CRLs can trigger out-of-bounds writes. The fix tightens parsing and bounds handling so CRL numbers cannot overflow the intended buffers.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
