Summary

Security update for openssl-1_1

Severity

Moderate

Notes

Title of the patch: Security update for openssl-1_1

Description of the patch: This update for openssl-1_1 to 1.1.0i fixes the following issues: These security issues were fixed: - 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) - Make problematic ECDSA sign addition length-invariant - Add blinding to ECDSA and DSA signatures to protect against side channel attacks These non-security issues were fixed: - When unlocking a pass phrase protected PEM file or PKCS#8 container, we now allow empty (zero character) pass phrases. - Certificate time validation (X509_cmp_time) enforces stricter compliance with RFC 5280. Fractional seconds and timezone offsets are no longer allowed. - Fixed a text canonicalisation bug in CMS - Add openssl(cli) Provide so the packages that require the openssl binary can require this instead of the new openssl meta package (bsc#1101470)

CVE-2018-0732 (GCVE-0-2018-0732)

Vulnerability from cvelistv5 – Published: 2018-06-12 13:00 – Updated: 2024-09-17 02:11

Title

Client DoS due to large DH parameter

Summary

During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause 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. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o).

Severity

No CVSS data available.

CWE

Client side Denial of Service

Assigner

openssl mitre root

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
