CVE-2020-12268 – jbig2dec: heap-based buffer overflow in jbig2_image_compose in jbig2_image.c
https://notcve.org/view.php?id=CVE-2020-12268
jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow. La función jbig2_image_compose en el archivo jbig2_image.c en Artifex jbig2dec versiones anteriores a la versión 0.18, tiene un desbordamiento de búfer en la región heap de la memoria. An integer overflow was found in jbig2dec, which causes an out-of-bounds read/write in the jbig2_image_compose function. This flaw could potentially result in the execution of code on the system. Applications that use jbig2dec with untrusted input may be vulnerable to this flaw. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00034.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20332 https://github.com/ArtifexSoftware/jbig2dec/commit/0726320a4b55078e9d8deb590e477d598b3da66e https://github.com/ArtifexSoftware/jbig2dec/compare/0.17...0.18 https://lists.debian.org/debian-lts-announce/2021/10/msg00023.html https://access.redhat.com/security/cve/CVE-2020-12268 https://bugzilla.redhat.com/show_bug.cgi?id=1848518 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2020-12137 – mailman: XSS via file attachments in list archives
https://notcve.org/view.php?id=CVE-2020-12137
GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code. GNU Mailman versiones 2.x anteriores a la versión 2.1.30, usa una extensión .obj para partes MIME de aplications/octet-stream. Este comportamiento puede contribuir a ataques de tipo XSS contra visitantes de archivos de lista, porque una respuesta HTTP desde un servidor web de archivo puede carecer de un tipo MIME, y un navegador web puede realizar rastreo del MIME, concluir que el tipo MIME debería haber sido text/html, y ejecutar código JavaScript. • http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/view/head:/NEWS http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00063.html http://www.openwall.com/lists/oss-security/2020/04/24/3 https://lists.debian.org/debian-lts-announce/2020/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6YCMGTTOXXCVM4O6CYZLTZDX6YLYORNF https://lists.fedoraproject.org • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
