Doc Text:
A flaw was found in Quill. An attacker with the ability to intercept and modify network traffic, such as through a TLS-intercepting proxy or a compromised certificate authority, could send an arbitrarily large HTTP response body during the Apple notarization process. This unbounded read of the response body into memory would cause the Quill client to run out of memory and crash, leading to a Denial of Service (DoS) for the application.

Description OSIDB Bzimport 2026-03-11 20:01:52 UTC 
Quill provides simple mac binary signing and notarization from any platform. Quill before version v0.7.1 has unbounded reads of HTTP response bodies during the Apple notarization process. Exploitation requires the ability to modify API responses from Apple's notarization service, which is not possible under standard network conditions due to HTTPS with proper TLS certificate validation; however, environments with TLS-intercepting proxies (common in corporate networks), compromised certificate authorities, or other trust boundary violations are at risk. When processing HTTP responses during notarization, Quill reads the entire response body into memory without any size limit. An attacker who can control or modify the response content can return an arbitrarily large payload, causing the Quill client to run out of memory and crash. The impact is limited to availability; there is no effect on confidentiality or integrity. Both the Quill CLI and library are affected when used to perform notarization operations. This vulnerability is fixed in 0.7.1.
