CyberRota Analysis
AI-GeneratedThe vulnerability affects the libpcap BPF interpreter, which fails to properly handle certain filter programs, potentially allowing crafted filters to access OS process memory beyond the intended buffer limits. This could lead to unauthorized memory reads, posing a risk of information disclosure on both 32-bit and 64-bit systems. Organizations utilizing libpcap in their network monitoring or packet capture solutions should prioritize addressing this vulnerability to mitigate potential data exposure risks.

Original NVD Description
libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures.
