DescriptionNVD

libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, two functions in camlibs/ptp2/ptp-pack.c accept a data pointer but no length parameter, performing unbounded reads. Their callers in ptp_unpack_EOS_events() have xsize available but never pass it, leaving both functions unable to validate reads against the actual buffer boundary. Commit 1817ecead20c2aafa7549dac9619fe38f47b2f53 patches the issue.

AnalysisAI

Out-of-bounds read in libgphoto2 versions up to 2.5.33 allows local attackers with physical access to a connected camera to read sensitive information from process memory or cause denial of service via malformed EOS event data. Two functions in ptp-pack.c lack length validation, enabling unbounded buffer reads when processing camera events. …
