Use After Free

An Arbitrary Free (Remote Code Execution) issue was discovered in Design Science MathType 6.9c. Crafted input can overwrite a structure, leading to a function call with an invalid parameter, and a subsequent free of important data such as a function pointer or list pointer. This is fixed in 6.9d.Show less

The __oom_reap_task_mm function in mm/oom_kill.c in the Linux kernel before 4.14.4 mishandles gather operations, which allows attackers to cause a denial of service (TLB entry leak or use-after-free) or possibly have unspecified other impact by triggering a copy_to_user call within a certain time window.Show less

An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability is an instance of a use after free vulnerability in the XFA engine, related to DOM manipulation. The vulnerability is triggered by crafted XFA script definitions in a PDF file. Successful exploitation could lead to arbitrary code execution.Show less

An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability is an instance of a use after free vulnerability in the JavaScript API related to bookmark functionality. The vulnerability is triggered by crafted JavaScript code embedded within a PDF file. A successful attack can lead to code corruption, control-flow hijack, or a code re-use attack.Show less

This vulnerability is an instance of a use after free vulnerability in the rendering engine. The vulnerability is triggered by a crafted PDF file containing a video annotation (and corresponding media files) that is activated by the embedded JavaScript. Successful exploitation could lead to arbitrary code execution.Show less

An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability is an instance of a use after free vulnerability. The vulnerability is triggered by a crafted PDF file that can cause a memory access violation exception in the XFA engine because of a dangling reference left as a consequence of freeing an object in the computation that manipulates internal nodes in a graph representation of a document object model used in XFA. Successful exploitation could lead to arbitrary code execution.Show less

An issue was discovered in secdrv.sys as shipped in Microsoft Windows Vista, Windows 7, Windows 8, and Windows 8.1 before KB3086255, and as shipped in Macrovision SafeDisc. Two carefully timed calls to IOCTL 0xCA002813 can cause a race condition that leads to a use-after-free. When exploited, an unprivileged attacker can run arbitrary code in the kernel.Show less

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Joyent SmartOS release-20170803-20170803T064301Z. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the SMBIOC_TREE_RELE ioctl. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code under the context of the host OS. Was ZDI-CAN-4984.Show less

Huawei Mate 9 Pro mobile phones with software of versions earlier than LON-AL00BC00B235 have a use after free (UAF) vulnerability. An attacker tricks a user into installing a malicious application, and the application can riggers access memory after free it. A local attacker may exploit this vulnerability to cause the mobile phone to crash.Show less

Artifex Mupdf version 1.12.0 contains a Use After Free vulnerability in fz_keep_key_storable that can result in DOS / Possible code execution. This attack appear to be exploitable via Victim opens a specially crafted PDF.Show less

Python 2.7.14 is vulnerable to a Heap-Buffer-Overflow as well as a Heap-Use-After-Free. Python versions prior to 2.7.14 may also be vulnerable and it appears that Python 2.7.17 and prior may also be vulnerable however this has not been confirmed. The vulnerability lies when multiply threads are handling large amounts of data. In both cases there is essentially a race condition that occurs. For the Heap-Buffer-Overflow, Thread 2 is creating the size for a buffer, but Thread1 is already writing to the buffer without knowing how much to write. So when a large amount of data is being processed, it is very easy to cause memory corruption using a Heap-Buffer-Overflow. As for the Use-After-Free, Thread3->Malloc->Thread1->Free's->Thread2-Re-uses-Free'd Memory. The PSRT has stated that this is not a security vulnerability due to the fact that the attacker must be able to run code, however in some situations, such as function as a service, this vulnerability can potentially be used by an attacker to violate a trust boundary, as such the DWF feels this issue deserves a CVE.Show less
