Name of the Vulnerable Software and Affected Versions
libgphoto2 versions prior to 2.5.34
Description
An out-of-bounds read exists in the
ptp unpack Sony DPD() function within camlibs/ptp2/ptp-pack.c. The issue occurs because the function reads the FormFlag byte using dtoh8o(data, *poffset) without performing a prior bounds check, unlike the standard ptp unpack DPD() function which validates the offset against the data length.Recommendations
Update to version 2.5.34 or later.
