Detection & IOCsextracted from sources · hover to see the quote
- →Trigger condition: hovering over or opening a malicious TTF font file in Windows Font Viewer is sufficient to trigger the out-of-bounds read in win32k!itrp_GetCVTEntryFast via the RCVT TrueType instruction handler. ↗
- →The vulnerability is triggered by a corrupted TTF font file causing win32k!itrp_GetCVTEntryFast to access an out-of-bounds CVT table index (up to 255) via the RCVT TrueType instruction, enabling kernel memory disclosure / KASLR bypass. ↗
- →Crash signature to look for in kernel crash dumps: BUGCHECK_STR 0x50 (PAGE_FAULT_IN_NONPAGED_AREA) with FAULTING_MODULE win32k and faulting function win32k!itrp_GetCVTEntryFast. ↗
- →Enable Special Pools for win32k.sys to reliably reproduce/detect crashes caused by this vulnerability during testing. ↗
- →The vulnerability can be used to disclose adjacent kernel pool memory contents to user-mode, potentially leaking sensitive kernel memory or facilitating a KASLR bypass, and may be chained with a remote code execution vulnerability. ↗
- ·The out-of-bounds read only affects win32k!itrp_GetCVTEntryFast (RCVT handler); the corresponding write instruction handler (WCVT) does not appear to be affected by the same problem. ↗
- ·The Office 2010 update for this CVE is not applicable on Windows Vista and later because the vulnerable code is not present in that configuration. ↗
- ·Customers running affected editions of Microsoft Lync 2013 (Skype for Business) must first install prerequisite updates 2965218 and 3039779 before applying the security update for this CVE. ↗

GDI+ Information Disclosure Vulnerability

CVE-2016-3209 [MEDIUM] GDI+ Information Disclosure Vulnerability
GDI+ Information Disclosure Vulnerability
Description: An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. An attacker who successfully exploited this vulnerability could use the retrieved information to circumvent Address Space Layout Randomization (ASLR) in Windows, which helps guard against a broad class of vulnerabilities. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability, such as a remote code execution vulnerability, that is capable of leveraging the ASLR circumvention.
