openSUSE Security Update : compat-openssl098 (openSUSE-2018-997)
Medium Nessus Plugin ID 117476
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis 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).
This update was imported from the SUSE:SLE-12:Update update project.
