Protection was added, to address CVE-2018-16858, to avoid a directory traversal attack where scripts in arbitrary locations on the file system could be executed. However this new protection could be bypassed by a URL encoding attack. In the fixed versions, the parsed url describing the script location is correctly encoded before further processing. This issue affects: Document Foundation LibreOffice versions prior to 6.2.6." } ] }, "generator": { "engine": "Vulnogram 0.0.7" }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-116 Improper Encoding or Escaping of Output" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "url": "https://www.libreoffice.org/about-us/security/advisories/CVE-2019-9852", "name": "https://www.libreoffice.org/about-us/security/advisories/CVE-2019-9852" }, { "refsource": "BUGTRAQ", "name": "20190815 [SECURITY] [DSA 4501-1] libreoffice security update", "url": "https://seclists.org/bugtraq/2019/Aug/28" }, { "refsource": "DEBIAN", "name": "DSA-4501", "url": "https://www.debian.org/security/2019/dsa-4501" }, { "refsource": "FEDORA", "name": "FEDORA-2019-2fe22a3a2c", "url": "https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH/" }, { "refsource": "UBUNTU", "name": "USN-4102-1", "url": "https://usn.ubuntu.com/4102-1/" }, { "refsource": "SUSE", "name": "openSUSE-SU-2019:2057", "url": "http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html" }, { "refsource": "BUGTRAQ", "name": "20190910 [SECURITY] [DSA 4519-1] libreoffice security update", "url": "https://seclists.org/bugtraq/2019/Sep/17" }, { "refsource": "SUSE", "name": "openSUSE-SU-2019:2183", "url": "http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20191006 [SECURITY] [DLA 1947-1] libreoffice security update", "url": "https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html" } ] }, "source": { "discovery": "EXTERNAL" } }
