A stack-based buffer overflow vulnerability exists in the libshared.so library of Cisco Linksys E1200 v2 routers running firmware version E1200_v2.0.11.001_us.tar.gz. The vulnerability arises from the use of sscanf with overly permissive "%100s" format specifiers in functions parsing /proc/net/arp entries, allowing local attackers to overflow fixed-size stack buffers. This can lead to memory corruption, denial of service, or potential arbitrary code execution.
