CyberRota Analysis
AI-GeneratedThe vulnerability allows authenticated users with permission to store analysis runs to submit malicious, highly compressed Base64-encoded zlib data that can expand to a much larger size during decompression. This can lead to denial of service by exhausting memory and disk space, as the entire decompressed output is held in memory before being written to disk. Organizations using CodeChecker should prioritize addressing this issue to prevent potential service disruptions.

Original NVD Description
CodeChecker's massStoreRun processing path performs one-shot decompression of attacker-controlled, Base64-encoded zlib data without enforcing a maximum decompressed size. An authenticated user with permission to store analysis runs can submit a highly compressed payload that expands to a significantly larger byte sequence. Because the entire decompressed output is materialized in memory before being written to a temporary file, a sufficiently large payload may exhaust process or host memory and consume substantial disk space, resulting in denial of service.
