Summary
CVE-2026-40334 affecting package libgphoto2 2.5.31-1
Details

libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, a missing null terminator exists in ptpunpackCanon_FE() in camlibs/ptp2/ptp-pack.c (line 1377). The function copies a filename into a 13-byte buffer using strncpy without explicitly null-terminating the result. If the source data is exactly 13 bytes with no null terminator, the buffer is left unterminated, leading to out-of-bounds reads in any subsequent string operation. Commit 259fc7d3bfe534ce4b114c464f55b448670ab873 patches the issue.
