A deserialization of untrusted data vulnerability exists in the Go implementation of Apache Fory, allowing an attacker to cause a denial of service by supplying crafted data with malformed type metadata. This triggers an uncaught panic, leading to service disruption. The issue affects Apache Fory versions from 0.16.0 up to but not including 1.5.0. The vulnerability is fixed in version 1.5.0, and users are advised to upgrade to this version to mitigate the risk.
AI Analysis
Technical Summary
The Go implementation of Apache Fory contains a deserialization vulnerability (CWE-502) where untrusted data containing malformed type metadata can cause an uncaught panic, resulting in a denial of service. This affects versions starting from 0.16.0 before 1.5.0. The vulnerability is resolved in version 1.5.0. Other language implementations of Apache Fory are not affected.
Potential Impact
An attacker can cause a denial of service by sending specially crafted data that triggers an uncaught panic in the Go implementation of Apache Fory. This disrupts normal service availability but does not indicate code execution or data disclosure based on the provided information.
Mitigation Recommendations
Users should upgrade to Apache Fory version 1.5.0, which contains the fix for this vulnerability. No other mitigation is indicated or required according to the available information.
