medium Nessus Plugin ID 307456
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of- bounds read in `ptp_unpack_DPV()` in `camlibs/ptp2/ptp-pack.c` (lines 622629). The UINT128 and INT128 cases advance `*offset += 16` without verifying that 16 bytes remain in the buffer. The entry check at line 609 only guarantees `*offset < total` (at least 1 byte available), leaving up to 15 bytes unvalidated. Commit 433bde9888d70aa726e32744cd751d7dbe94379a patches the issue. (CVE-2026-40335)
Note that Nessus relies on the presence of the package as reported by the vendor.
