CVE-2018-18820 We released a new version of Icecast. It is a security release and we recommend to update all Icecast installations of versions below 2.4.4 to it. - Fix buffer overflows in URL auth code, [CVE-2018-18820]. [#2342] * This security issue affects all Icecast servers running version 2.4.0, 2.4.1, 2.4.2 or 2.4.3 if there is a "mount" definition that enables URL authentication. * A malicious client could send long HTTP headers, leading to a buffer overflow and potential remote code execution. * The problematic code was introduced in version 2.4.0 and was now brought to our attention by Nick Rolfe of Semmle Security Research Team https://lgtm.com/security https://gitlab.xiph.org/xiph/icecast-server/commit/b21a7283bd1598c5af0bbb250a041ba8198f98f2 - Worked around buffer overflows in URL auth's cURL interface. * We currently do not believe that this issue is exploitable. It would require a malicious URL authentication back end server to send a crafted payload and make it through libcURL. * If someone manages, please let us know. https://gitlab.xiph.org/xiph/icecast-server/commit/03ea74c04a5966114c2fe66e4e6892d11a68181e Source: http://downloads.xiph.org/releases/icecast/icecast-2.4.4.tar.gz [#2342]: https://gitlab.xiph.org/xiph/icecast-server/issues/2342 Thomas B.
