In DjVuLibre 3.5.27, the sorting functionality (aka GArrayTemplate<TYPE>::sort) allows attackers to cause a denial-of-service (application crash due to an Uncontrolled Recursion) by crafting a PBM image file that is mishandled in libdjvu/GContainer.h. En DjVuLibre versión 3.5.27, la funcionalidad de clasificación (también conocida como GArrayTemplate(TYPE)::sort), permite a atacantes causar una denegación de servicio (bloqueo de aplicación debido a una recursión no controlada) mediante el diseño de un archivo de imagen PBM que es manejado inapropiadamente en el archivo libdjvu/GContainer.h. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00086.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00087.html https://lists.debian.org/debian-lts-announce/2019/08/msg00036.html https://lists.debian.org/debian-lts-announce/2021/05/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FPMG3VY33XGMIKE6QDYIUVS6A7GNTHTK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JO65AWU7LEWNF6DDCZPRFTR2ZPP5X • CWE-674: Uncontrolled Recursion •

DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-bounds read) by crafting a corrupted JB2 image file that is mishandled in JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in libdjvu/GBitmap.h. DjVuLibre versión 3.5.27, permite a atacantes causar un ataque de denegación de servicio (bloqueo de aplicación por medio de una lectura fuera de límites) mediante el diseño de un archivo de imagen JB2 corrupto que es manejado inapropiadamente en la función JB2Dict::JB2Codec::get_direct_context en el archivo libdjvu/JB2Image.h debido a una falta de comprobación de cero bytes en el archivo libdjvu/GBitmap.h. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00086.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00087.html https://lists.debian.org/debian-lts-announce/2019/08/msg00036.html https://lists.debian.org/debian-lts-announce/2021/05/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FPMG3VY33XGMIKE6QDYIUVS6A7GNTHTK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JO65AWU7LEWNF6DDCZPRFTR2ZPP5X • CWE-125: Out-of-bounds Read •
CVSS: 7.8EPSS: 0%CPEs: 10EXPL: 0CVE-2019-9852 – Insufficient URL encoding flaw in allowed script location check
https://notcve.org/view.php?id=CVE-2019-9852
LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. 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. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH https://seclists.org/bugtraq/2019/Aug/28 https://seclists.org/bugtraq/2019/Sep/17 https://usn.ubuntu.com/4102-1 https://www.debian.org/security/2019/dsa-4 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-116: Improper Encoding or Escaping of Output •
CVSS: 9.8EPSS: 96%CPEs: 10EXPL: 1CVE-2019-9851 – LibreLogo global-event script execution
https://notcve.org/view.php?id=CVE-2019-9851
LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. Protection was added, to address CVE-2019-9848, to block calling LibreLogo from document event script handers, e.g. mouse over. However LibreOffice also has a separate feature where documents can specify that pre-installed scripts can be executed on various global script events such as document-open, etc. In the fixed versions, global script event handlers are validated equivalently to document script event handlers. This issue affects: Document Foundation LibreOffice versions prior to 6.2.6. • https://www.exploit-db.com/exploits/47298 http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00067.html http://packetstormsecurity.com/files/154168/LibreOffice-Macro-Python-Code-Execution.html https://lists.debian.org/debian-lts-announce/2019/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PMEGUWMWORC3DOVEHVXLFT3A5RSCMLBH https://seclists.org/bugtraq/2019/Aug/28 htt • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •

LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added, to address CVE-2019-9848, to block calling LibreLogo from script event handers. However an insufficient url validation vulnerability in LibreOffice allowed malicious to bypass that protection and again trigger calling LibreLogo from script event handlers.
