Vulnerability from csaf_suse - Published: 2018-09-10 16:00 - Updated: 2018-09-10 16:00
Summary
Security update for compat-openssl098
Severity
Moderate
Notes
Title of the patch: Security update for compat-openssl098
Description of the patch: This update for compat-openssl098 fixes the following security issues: - CVE-2018-0732: During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server could have sent a very large prime value to the client. This caused the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack (bsc#1097158) - Blinding enhancements for ECDSA and DSA (bsc#1097624, bsc#1098592) - CVE-2018-0737: The RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could have recovered the private key (bsc#1089039) - CVE-2018-0739: Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could have resulted in DoS (bsc#1087102).
