CWE-770

Description

When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.

Affected configurations

• haxx curl (>= 7.84.0 < 8.3.0) • fedoraproject fedora 37 • fedoraproject fedora 38 • fedoraproject fedora 39 • microsoft windows 10 1809 (< 10.0.17763.5122) • microsoft windows 10 21h2 (< 10.0.19044.3693) • microsoft windows 10 22h2 (< 10.0.19045.3693) • microsoft windows 11 21h2 (< 10.0.22000.2600) • microsoft windows 11 22h2 (< 10.0.22621.2715) • microsoft windows 11 23h2 (< 10.0.22631.2715) • microsoft windows server 2019 (< 10.0.17763.5122) • microsoft windows server 2022 (< 10.0.20348.2113)
