CVSS: 3.5EPSS: 0%CPEs: 7EXPL: 0CVE-2020-11058 – Improper Restriction of Operations within the Bounds of a Memory Buffer in FreeRDP
https://notcve.org/view.php?id=CVE-2020-11058
In FreeRDP after 1.1 and before 2.0.0, a stream out-of-bounds seek in rdp_read_font_capability_set could lead to a later out-of-bounds read. As a result, a manipulated client or server might force a disconnect due to an invalid data read. This has been fixed in 2.0.0. En FreeRDP versiones posteriores a 1.1 y anteriores a 2.0.0, una búsqueda fuera de límites de flujo de datos en rdp_read_font_capability_set podría conllevar a una posterior lectura fuera de límites. Como resultado, un cliente o servidor manipulado podría forzar una desconexión debido a una lectura de datos no válida. • https://github.com/FreeRDP/FreeRDP/commit/3627aaf7d289315b614a584afb388f04abfb5bbf https://github.com/FreeRDP/FreeRDP/issues/6011 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-wjg2-2f82-466g https://lists.debian.org/debian-lts-announce/2020/08/msg00054.html https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://usn.ubuntu.com/4379-1 https://usn.ubuntu.com/4382-1 https://access.redhat.com/security/cve/CVE-2020-11058 https://bugzilla.redhat.com/show_bug&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
