CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 0CVE-2020-35524 – libtiff: Heap-based buffer overflow in TIFF2PDF tool
https://notcve.org/view.php?id=CVE-2020-35524
A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se encontró un error de desbordamiento de búfer en la región heap de la memoria en libtiff en el manejo de imágenes TIFF en la herramienta TIFF2PDF de libtiff. Un archivo TIFF especialmente diseñado puede conllevar a una ejecución de código arbitraria. • https://bugzilla.redhat.com/show_bug.cgi?id=1932044 https://gitlab.com/libtiff/libtiff/-/merge_requests/159 https://gitlab.com/rzkn/libtiff/-/commit/7be2e452ddcf6d7abca88f41d3761e6edab72b22 https://lists.debian.org/debian-lts-announce/2021/06/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMHBYFMX3D5VGR6Y3RXTTH3Q4NF4E6IG https://security.gentoo.org/glsa/202104-06 https://security.netapp.com/advisory/ntap-20210521-0009 https://www.debian.org/se • CWE-787: Out-of-bounds Write •
