Subject: [PATCH v7 10/12] http: replace unsafe size_t multiplication with st_mult
Date: Fri, 20 Jan 2023 22:08:48 +0000 [thread overview]
Message-ID: <4b1635b3f6968f8d755bdf6bc4ec7af77aefd315.1674252531.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1352.v7.git.1674252530.gitgitgadget@gmail.com>
From: Matthew John Cheetham <mjcheetham@outlook.com>
Replace direct multiplication of two size_t parameters in curl response
stream handling callback functions with `st_mult` to guard against
overflows.
