Описание
Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, Netty's DnsResolveContext fails to validate the origin (bailiwick) of CNAME records in DNS responses. Versions 4.1.135.Final and 4.2.15.Final patch the issue.
A flaw was found in Netty's DnsResolveContext. This vulnerability allows a remote attacker to achieve information disclosure or data manipulation by crafting malicious DNS responses. The flaw occurs because the DnsResolveContext fails to validate the origin (bailiwick) of CNAME records in DNS responses, which could enable an attacker to redirect network traffic or intercept sensitive data from affected applications.
Отчет
This Important severity flaw in Netty's DnsResolveContext allows a remote attacker to achieve information disclosure or data manipulation. By crafting malicious DNS responses, an attacker could redirect network traffic or intercept sensitive data, impacting applications utilizing Netty for DNS resolution in Red Hat products.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
