Insufficient access control in driver stack for Intel QuickAssist Technology for Linux before version 4.2 may allow an unprivileged user to potentially disclose information via local access.

Last week at BlueHat’s “MSRC Listens” session, I took the stage with Mechele Gruhn, manager of the Vulnerability Response PM team, to explain how MSRC is changing our communication, workflows, and tooling to deliver an improved user experience for our partners in the security research community. We promised to communicate more about what’s happening in the MSRC that affects our customers and research partners.

An exploitable out-of-bounds write exists in the TIFF-parsing functionality of Canvas Draw version 5.0.0. An attacker can deliver a TIFF image to trigger this vulnerability and gain code execution.

An exploitable uninitialized length vulnerability exists within the Word document-parser of the Atlantis Word Processor 3.0.2.3 and 3.0.2.5. A specially crafted document can cause Atlantis to skip initializing a value representing the number of columns of a table. Later, the application will use this as a length within a loop that will write to a pointer on the heap. Due to this value being controlled, a buffer overflow will occur, which can lead to code execution under the context of the application. An attacker must convince a victim to open a document in order to trigger this vulnerability.

An exploitable heap-based buffer overflow vulnerability exists in the Windows enhanced metafile parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted image embedded within a document can cause an undersized allocation, resulting in an overflow when the application tries to copy data into it. An attacker must convince a victim to open a document in order to trigger this vulnerability.

An exploitable stack-based buffer overflow vulnerability exists in the JPEG parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted image embedded within a document can cause a length to be miscalculated and underflow. This length is then treated as unsigned and then used in a copying operation. Due to the length underflow, the application will then write outside the bounds of a stack buffer, resulting in a buffer overflow. An attacker must convince a victim to open a document in order to trigger this vulnerability.

An exploitable uninitialized pointer vulnerability exists in the Office Open XML parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted document can cause an uninitialized pointer representing a TTableRow to be assigned to a variable on the stack. This variable is later dereferenced and then written to allow for controlled heap corruption, which can lead to code execution under the context of the application. An attacker must convince a victim to open a document in order to trigger this vulnerability.

An exploitable double-free vulnerability exists in the Office Open XML parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted document can cause a TTableRow instance to be referenced twice, resulting in a double-free vulnerability when both the references go out of scope. An attacker must convince a victim to open a document in order to trigger this vulnerability.

DLL Search Order Hijacking vulnerability in Microsoft Windows Client in McAfee True Key (TK) before 5.1.165 allows local users to execute arbitrary code via specially crafted malware.

Accessing, modifying, or executing executable files vulnerability in Microsoft Windows client in McAfee Application and Change Control (MACC) 8.0.0 Hotfix 4 and earlier allows authenticated users to execute arbitrary code via file transfer from external system.
