Kofax Power PDF PDF File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kofax Power PDF. 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 parsing of PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22921.Show less

A vulnerability regarding buffer copy without checking the size of input ('Classic Buffer Overflow') has been found in the login component. This allows remote attackers to write specific files containing non-sensitive information and conduct limited denial-of-service attacks via unspecified vectors. This attack only affects the login service which will automatically restart. The following models with Synology Camera Firmware versions before 1.1.1-0383 may be affected: BC500 and TC500.Show less

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
