Improper Validation of Array Index
Overview Affected versions of this package are vulnerable to Improper Validation of Array Index when sending a malformed packet with the correct length. An attacker can crash the system or cause an out of bounds read by exploiting this vulnerability. Remediation Upgrade wolfssl to version 5.7.0 o...
Unspecified vulnerability in wolfSSL (CNVD-2024-37452)
wolfSSL CyaSSL is the United States wolfSSL company for embedded systems developers to use a small, portable embedded SSL programming library. A security vulnerability exists in wolfSSL versions prior to 5.6.6, which can be exploited by an attacker to trigger a 5-byte buffer out-of-bounds read...
wolfSSL Input Validation Error Vulnerability
wolfSSL CyaSSL is the United States wolfSSL company for embedded systems developers to use a small, portable embedded SSL programming library. An input validation error vulnerability exists in WolfSSL versions prior to 5.6.6, which stems from a failure to check if a message crosses a key boundary...
Unspecified vulnerability in wolfSSL (CNVD-2024-37453)

CVE-2023-6936 Heap-buffer over-read with WOLFSSL_CALLBACKS
In wolfSSL prior to 5.6.6, if callback functions are enabled via the WOLFSSLCALLBACKS flag, then a malicious TLS client or network attacker can trigger a buffer over-read on the heap of 5 bytes WOLFSSLCALLBACKS is only intended for debugging...
CVE-2023-6937
wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a result, it was possible to combine DTLS messages using different keys into one DTLS record. The most extreme edge case is that, in DTLS 1.3, it was possible that an unencrypted DTLS 1.3 record...
CVE-2023-6937 Improper (D)TLS key boundary enforcement

Name of the Vulnerable Software and Affected Versions WolfSSL affected versions not specified Description The issue is related to the generation of the ECDSA nonce k, where a random number r is selected and then reduced modulo n, the order of the elliptic curve. The division used during the...
Insecure Randomness
Overview Affected versions of this package are vulnerable to Insecure Randomness. If a TLS 1.3 client gets neither a PSK pre shared key extension nor a KSE key share extension when connecting to a malicious server, a default predictable buffer gets used for the IKM Input Keying Material value whe...

CVE-2022-42905
In wolfSSL before 5.5.2, if callback functions are enabled via the WOLFSSLCALLBACKS flag, then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. WOLFSSLCALLBACKS is only intended for debugging...
DEBIAN-CVE-2022-42961
An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via ...
