wolfSSL.wolfssl is vulnerable to Buffer overflow (stack based)
22
Low Risk
This Affects:
wolfSSL.wolfsslTL;DR
wc_PKCS7_EncodeSignedData and wc_PKCS7_EncodeSignedData_ex write signed attributes into a fixed-size array when encoding PKCS#7 SignedData; more than seven signed attributes causes a stack out-of-bounds write. Only custom PKCS#7 signing with many attributes triggers the issue. The fix enforces limits or sizing so the buffer cannot be overrun.
