4,227 CVEs • Abstraction: Base • Likelihood of Exploit: High

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.

A vulnerability, which was classified as critical, has been found in bwoodsend rockhopper up to 0.1.2. Affected by this issue is the function count_rows of the file rockhopper/src/ragged_array.c of the component Binary Parser. The manipulation of the argument raw leads to buffer overflow. Local access is required to approach this attack. Upgrading to version 0.2.0 is able to address this issue. The name of the patch is 1a15fad5e06ae693eb9b8908363d2c8ef455104e. It is recommended to upgrade the affected component. The identifier of this vulnerability is VDB-266312.Show less

TP-Link Omada ER605 Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the handling of DNS names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22523.Show less

In RTI Connext Professional 5.3.1 through 6.1.0 before 6.1.1, a buffer overflow in XML parsing from Routing Service, Recording Service, Queuing Service, and Cloud Discovery Service allows attackers to execute code with the affected service's privileges, compromise the service's integrity, leak sensitive information, or crash the service. These attacks could be done via a remote malicious RTPS message; a compromised call with malicious parameters to the RTI_RoutingService_new, rti::recording::Service, RTI_QueuingService_new, or RTI_CDS_Service_new public APIs; or a compromised local file system containing a malicious XML file.Show less

In the Linux kernel, the following vulnerability has been resolved: vt: fix unicode buffer corruption when deleting characters This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.Show less
