http://bugzilla.opensuse.org/show_bug.cgi?id=1114434 Bug ID: 1114434 Summary: VUL-1: CVE-2018-18820: [buffer overflow in url-auth] Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other URL: https://smash.suse.de/issue/218491/ OS: Other Status: NEW Severity: Minor Priority: P5 - None Component: Security Assignee: tiwai@suse.com Reporter: kbabioch@suse.com QA Contact: security-team@suse.de Found By: Security Response Team Blocker: --- 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/b21a7283bd1598c5af0bbb250... - 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/03ea74c04a5966114c2fe66e4...
