#buffer_overflow

An issue was discovered in the function mark_beginning_as_normal in nfa.c in flex 2.6.4. There is a stack exhaustion problem caused by the mark_beginning_as_normal function making recursive calls to itself in certain scenarios involving lots of '*' characters. Remote attackers could leverage this vulnerability to cause a denial-of-service.

An issue was discovered in Anti-Grain Geometry (AGG) 2.4 as used in SVG++ (aka svgpp) 1.2.3. A heap-based buffer overflow bug in svgpp_agg_render may lead to code execution. In the render_scanlines_aa_solid function, the blend_hline function is called repeatedly multiple times. blend_hline is equivalent to a loop containing write operations. Each call writes a piece of heap data, and multiple calls overwrite the data in the heap.

KMPlayer 4.2.2.15 and earlier have a Heap Based Buffer Overflow Vulnerability. It could be exploited with a crafted FLV format file. The problem is that more frame data is copied to heap memory than the size specified in the frame header. This results in a memory corruption and remote code execution.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h because the number of program headers is not restricted.

An exploitable remote code execution vulnerability exists in the HTTP header-parsing function of the TP-Link TL-R600VPN HTTP Server. A specially crafted HTTP request can cause a buffer overflow, resulting in remote code execution on the device. An attacker can send an authenticated HTTP request to trigger this vulnerability.

An exploitable remote code execution vulnerability exists in the ping and tracert functionality of the TP-Link TL-R600VPN HWv3 FRNv1.3.0 and HWv2 FRNv1.2.3 http server. A specially crafted IP address can cause a stack overflow, resulting in remote code execution. An attacker can send a single authenticated HTTP request to trigger this vulnerability.

DENX U-Boot through 2018.09-rc1 has a remotely exploitable buffer overflow via a malicious TFTP server because TFTP traffic is mishandled. Also, local exploitation can occur via a crafted kernel image.

An exploitable firmware downgrade vulnerability exists in the time syncing functionality of Yi Home Camera 27US 1.8.7.0D. A specially crafted packet can cause a buffer overflow, resulting in code execution. An attacker can intercept and alter network traffic to trigger this vulnerability.

An exploitable code execution vulnerability exists in the QR code scanning functionality of Yi Home Camera 27US 1.8.7.0D. A specially crafted QR Code can cause a buffer overflow, resulting in code execution. The trans_info call can overwrite a buffer of size 0x104, which is more than enough to overflow the return address from the ssid_dst field.

An exploitable code execution vulnerability exists in the QR code scanning functionality of Yi Home Camera 27US 1.8.7.0D. A specially crafted QR Code can cause a buffer overflow, resulting in code execution. An attacker can make the camera scan a QR code to trigger this vulnerability. Alternatively, a user could be convinced to display a QR code from the internet to their camera, which could exploit this vulnerability.
