CVE-2020-24585
An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS applicationdata messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application...
CVE-2020-15309: Concurrent Execution using Shared Resource with Improper Synchronization
An issue was discovered in wolfSSL before 4.5.0, when single precision is not employed. Local attackers can conduct a cache-timing attack against public key operations. These attackers may already have obtained sensitive information if the affected system has been used for private key operations...
CVE-2020-24585: Undefined Security Weakness
An issue was discovered in the DTLS handshake implementation in wolfSSL before 4.5.0. Clear DTLS applicationdata messages in epoch 0 do not produce an out-of-order error. Instead, these messages are returned to the application...
CVE-2020-12457: Loop with Unreachable Exit Condition
An issue was discovered in wolfSSL before 4.5.0. It mishandles the changecipherspec CCS message processing logic for TLS 1.3. If an attacker sends ChangeCipherSpec messages in a crafted way involving more than one in a row, the server becomes stuck in the ProcessReply loop, i.e., a denial of...
PT-2020-14347 · Wolfssl · Wolfssl
Name of the Vulnerable Software and Affected Versions: wolfSSL versions prior to 4.5.0 Description: An issue allows local attackers to conduct a cache-timing attack against public key operations. This could potentially expose sensitive information if the affected system has been used for private...
wolfSSL encryption issue vulnerability (CNVD-2020-50525)
wolfSSL formerly known as 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 the ecc.c file in wolfSSL versions prior to 4.4.0. No details of the vulnerability are provided at th...
Timing Attack
wolfssl.native is vulnerable to timing attack. Operations involving a private key such as key generation or signing in ecc.c fails to use a constant-time modular inverse when mapping to affine coordinates, leaking sensitive coordinates when an attacker can take advantage of timing variations in...
CVE-2020-11735
The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak."...

CVE-2020-11735
The CVE-2020-11735 issue affects wolfSSL’s ECC implementation (ecc.c) in versions prior to 4.4.0, where private-key operations do not use a constant-time modular inverse when mapping to affine coordinates, causing a projective coordinates leak. This is treated as a timing-related vulnerability af...
CVE-2020-11735: Observable Discrepancy
The private-key operations in ecc.c in wolfSSL before 4.4.0 do not use a constant-time modular inverse when mapping to affine coordinates, aka a "projective coordinates leak."...
CVE-2019-9498
A flaw was found in wpasupplicant. An attack using invalid scalar/element values is possible against the EAP-pwd server since hostapd and wpasupplicant did not validate these values in the received EAP-pwd-Commit messages. When processing an EAP-pwd Commit frame, the peer's scalar and element...
