Description
libgphoto2 through 2.5.34 contains stack-based and heap-based buffer overflow vulnerabilities in jl2005c_init() that allow malicious USB devices to corrupt memory by supplying an unbounded allocation table entry count. Attackers can connect a spoofed Jeilin JL2005B/C/D camera reporting 1022 or more entries to overwrite the saved return address and heap data, potentially achieving code execution.
