MatrixSSL before 3.8.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted ASN.1 Bit Field primitive in an X.509 certificate.
AnalysisAI
MatrixSSL before 3.8.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted ASN.1 Bit Field primitive in an X.509 certificate. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. MatrixSSL before 3.8.6 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted ASN.1 Bit Field primitive in an X.509 certificate. Affected products include: Matrixssl. Version information: before 3.8.6.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
