Title

Digia Qt拒绝服务漏洞

Description

Digia Qt是芬兰Digia公司的一套跨平台的C++应用程序开发框架。该框架可用于开发GUI程序。Mumble是一套用于游戏中的语音通讯工具。该工具可以让玩家在玩游戏的同时进行实时的语音交流。 Digia Qt 5.12.2版本至5.14.2版本（用于Mumble 1.3.0非官方版本和其他产品）中存在安全漏洞，该漏洞源于程序在OpenSSL握手过程中未能正确调用‘SSL_shutdown’函数。攻击者可利用该漏洞导致TLS应用程序拒绝服务。

CVE-2020-13962 (GCVE-0-2020-13962)

Vulnerability from cvelistv5 – Published: 2020-06-08 23:14 – Updated: 2024-08-04 12:32

Summary

Qt 5.12.2 through 5.14.2, as used in unofficial builds of Mumble 1.3.0 and other products, mishandles OpenSSL's error queue, which can cause a denial of service to QSslSocket users. Because errors leak in unrelated TLS sessions, an unrelated session may be disconnected when any handshake fails. (Mumble 1.3.1 is not affected, regardless of the Qt version.)

Severity

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.
