CVSS: 9.8EPSS: 7%CPEs: 15EXPL: 1CVE-2018-8787 – freerdp: Integer overflow leading to heap-based buffer overflow in gdi_Bitmap_Decompress() function
https://notcve.org/view.php?id=CVE-2018-8787
FreeRDP prior to version 2.0.0-rc4 contains an Integer Overflow that leads to a Heap-Based Buffer Overflow in function gdi_Bitmap_Decompress() 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 desbordamiento de enteros que conduce a un desbordamiento de búfer basado en memoria dinámica (heap) en la función gdi_Bitmap_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 before versions 2.0.0-rc4. An integer overflow that leads to a heap-based buffer overflow in the gdi_Bitmap_Decompress() function leads to 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/09b9d4f1994a674c4ec85b4947aa656eda1aed8a https://lists.debian.org/debian-lts-announce/2019/02/msg00015.html 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://access.redhat.com/security/cve/CVE-2018-8787 https://bugzilla.redhat.com/show_bug.cgi?id=1671361 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow CWE-787: Out-of-bounds Write •
