Heap-based Buffer Overflow

Delta Electronics TPEditor, Versions 1.94 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, which may allow an attacker to remotely execute arbitrary code.Show less

An exploitable command execution vulnerability exists in the ASN1 certificate writing functionality of Openweave-core version 4.0.2. A specially crafted weave certificate can trigger a heap-based buffer overflow, resulting in code execution. An attacker can craft a weave certificate to trigger this vulnerability.Show less

An exploitable code execution vulnerability exists in the XCF image rendering functionality of SDL2_image 2.0.4. A specially crafted XCF image can cause a heap overflow, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.Show less

An exploitable code execution vulnerability exists in the PCX image-rendering functionality of SDL2_image 2.0.4. A specially crafted PCX image can cause a heap overflow, resulting in code execution. An attacker can display a specially crafted image to trigger this vulnerability.Show less

Delta Electronics CNCSoft ScreenEditor, Versions 1.00.89 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. There is a lack of user input validation before copying data from project files onto the heap.Show less

Call to the scrypt_enc() function in HHVM can lead to heap corruption by using specifically crafted parameters (N, r and p). This happens if the parameters are configurable by an attacker for instance by providing the output of scrypt_enc() in a context where Hack/PHP code would attempt to verify it by re-running scrypt_enc() with the same parameters. This could result in information disclosure, memory being overwriten or crashes of the HHVM process. This issue affects versions 4.3.0, 4.4.0, 4.5.0, 4.6.0, 4.7.0, 4.8.0, versions 3.30.5 and below, and all versions in the 4.0, 4.1, and 4.2 series.Show less

A heap-buffer overflow vulnerability was found in the Redis hyperloglog data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before 5.0.4. By carefully corrupting a hyperloglog using the SETRANGE command, an attacker could trick Redis interpretation of dense HLL encoding to write up to 3 bytes beyond the end of a heap-allocated buffer.Show less

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S9 prior to January 2019 Security Update (SMR-JAN-2019 - SVE-2018-13467). User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the ASN.1 parser. When parsing ASN.1 strings, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-7472.Show less

A buffer overflow vulnerability in WhatsApp VOIP stack allowed remote code execution via specially crafted series of RTCP packets sent to a target phone number. The issue affects WhatsApp for Android prior to v2.19.134, WhatsApp Business for Android prior to v2.19.44, WhatsApp for iOS prior to v2.19.51, WhatsApp Business for iOS prior to v2.19.51, WhatsApp for Windows Phone prior to v2.18.348, and WhatsApp for Tizen prior to v2.18.15.Show less

DaviewIndy 8.98.7 and earlier versions have a Heap-based overflow vulnerability, triggered when the user opens a malformed JPEG2000 format file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.Show less

DaviewIndy 8.98.7 and earlier versions have a Heap-based overflow vulnerability, triggered when the user opens a malformed DIB format file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.Show less

Delta Industrial Automation CNCSoft, CNCSoft ScreenEditor Version 1.00.88 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by processing specially crafted project files, allowing an attacker to remotely execute arbitrary code. There is a lack of user input validation before copying data from project files onto the heap.Show less

Multiple heap-based buffer overflow vulnerabilities exist in Honeywell Experion PKS all versions prior to R400.6, all versions prior to R410.6, and all versions prior to R430.2 modules, which could lead to possible remote code execution or denial of service. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.Show less

UltraVNC revision 1211 has a heap buffer overflow vulnerability in VNC server code inside file transfer offer handler, which can potentially in result code execution. This attack appears to be exploitable via network connectivity. This vulnerability has been fixed in revision 1212.Show less
