CVE-2018-8786 – freerdp: Integer truncation leading to heap-based buffer overflow in update_read_bitmap_update() function
https://notcve.org/view.php?id=CVE-2018-8786
FreeRDP prior to version 2.0.0-rc4 contains an Integer Truncation that leads to a Heap-Based Buffer Overflow in function update_read_bitmap_update() and results in a memory corruption and probably even a remote code execution. FreeRDP en versiones anteriores a la 2.0.0-rc4 contiene un truncamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función zgfx_decompress() y que resulta en una corrupción de memoria y, probablemente, incluso en la ejecución remota de código. A flaw was found in freerdp in versions prior to version 2.0.0-rc4. An integer truncation that leads to a heap-based buffer overflow in the update_read_bitmap_update() function results in a memory corruption. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://www.securityfocus.com/bid/106938 https://access.redhat.com/errata/RHSA-2019:0697 https://github.com/FreeRDP/FreeRDP/commit/445a5a42c500ceb80f8fa7f2c11f3682538033f3 https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YVJKO2DR5EY4C4QZOP7SNNBEW2JW6FHX https://research.checkpoint.com/reverse-rdp-attack-code-execution-on-rdp-clients https://usn.ubuntu.com/3845-1 https://usn.ubuntu.com/3845-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-680: Integer Overflow to Buffer Overflow CWE-681: Incorrect Conversion between Numeric Types CWE-787: Out-of-bounds Write •
