Doc Text:
A flaw was found in libgphoto2. An attacker can execute arbitrary code or cause a denial of service (DoS) by connecting a malicious USB device to the system. This vulnerability occurs because the jl2005c camera driver fails to validate the allocation table entry count during device initialization, leading to stack- and heap-based buffer overflows.

Description OSIDB Bzimport 2026-11-06 19:41:20 UTC 
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.
