Heap-based Buffer Overflow

In libIEC61850 before version 1.4.3, when a message with COTP message length field with value < 4 is received an integer underflow will happen leading to heap buffer overflow. This can cause an application crash or on some platforms even the execution of remote code. If your application is used in open networks or there are untrusted nodes in the network it is highly recommend to apply the patch. This was patched with commit 033ab5b. Users of version 1.4.x should upgrade to version 1.4.3 when available. As a workaround changes of commit 033ab5b can be applied to older versions.Show less

Delta Electronics TPEditor Versions 1.97 and prior. A heap-based buffer overflow may be exploited by processing a specially crafted project file. Successful exploitation of this vulnerability may allow an attacker to read/modify information, execute arbitrary code, and/or crash the application.Show less

Advantech WebAccess HMI Designer, Versions 2.1.9.31 and prior. Multiple heap-based buffer overflow vulnerabilities may be exploited by opening specially crafted project files that may overflow the heap, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.Show less

There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow.Show less

There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow.Show less

DaviewIndy 8.98.4 and earlier version contain Heap-based overflow vulnerability, triggered when the user opens a malformed specific file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.Show less

DaviewIndy 8.98.4 and earlier version contain Heap-based overflow vulnerability, triggered when the user opens a malformed specific file that is mishandled by Daview.exe. Attackers could exploit this and arbitrary code execution.Show less

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R6700 V1.0.4.84_10.0.58 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of string table file uploads. The issue results from the lack of proper validation of 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 web server. Was ZDI-CAN-9767.Show less

In Bareos Director less than or equal to 16.2.10, 17.2.9, 18.2.8, and 19.2.7, a heap overflow allows a malicious client to corrupt the director's memory via oversized digest strings sent during initialization of a verify job. Disabling verify jobs mitigates the problem. This issue is also patched in Bareos versions 19.2.8, 18.2.9 and 17.2.10.Show less

Delta Industrial Automation DOPSoft, Version 4.00.08.15 and prior. Opening a specially crafted project file may overflow the heap, which may allow remote code execution, disclosure/modification of information, or cause the application to crash.Show less

A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3), SIMATIC PDM (All versions < V9.2), SIMATIC STEP 7 V5.X (All versions < V5.6 SP2 HF3), SINAMICS STARTER (containing STEP 7 OEM version) (All versions < V5.4 HF2). A buffer overflow vulnerability could allow a local attacker to cause a Denial-of-Service situation. The security vulnerability could be exploited by an attacker with local access to the affected systems. Successful exploitation requires user privileges but no user interaction. The vulnerability could allow an attacker to compromise the availability of the system as well as to have access to confidential information.Show less

Advantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Multiple heap-based buffer overflow vulnerabilities exist caused by a lack of proper validation of the length of user-supplied data, which may allow remote code execution.Show less

There is a buffer overwrite vulnerability in the Quram qmg library of Samsung's Android OS versions O(8.x), P(9.0) and Q(10.0). An unauthenticated, unauthorized attacker sending a specially crafted MMS to a vulnerable phone can trigger a heap-based buffer overflow in the Quram image codec leading to an arbitrary remote code execution (RCE) without any user interaction. The Samsung ID is SVE-2020-16747.Show less

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.7.1.29511. 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 handling of U3D objects in PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-10192.Show less

A Heap-based Buffer Overflow was found in Emerson OpenEnterprise SCADA Server 2.83 (if Modbus or ROC Interfaces have been installed and are in use) and all versions of OpenEnterprise 3.1 through 3.3.3, where a specially crafted script could execute code on the OpenEnterprise Server.Show less

An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.Show less

The Broadcom wl WiFi driver is vulnerable to a heap buffer overflow. If the vendor information element data length is larger than 164 bytes, a heap buffer overflow is triggered in wlc_wpa_plumb_gtk. In the worst case scenario, by sending specially-crafted WiFi packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. More typically, this vulnerability will result in denial-of-service conditions.Show less
