Описание
libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have a memory leak in ptp_unpack_Sony_DPD() in camlibs/ptp2/ptp-pack.c (lines 884–885). When processing a secondary enumeration list (introduced in 2024+ Sony cameras), the function overwrites dpd->FORM.Enum.SupportedValue with a new calloc() without freeing the previous allocation from line 857. The original array and any string values it contains are leaked on every property descriptor parse. Commit 404ff02c75f3cb280196fc260a63c4d26cf1a8f6 fixes the issue.
A flaw was found in libgphoto2, a camera access and control library. When processing a secondary enumeration list from certain Sony cameras, the ptp_unpack_Sony_DPD() function improperly handles memory allocation. This oversight causes a memory leak, which can lead to resource exhaustion and potentially result in a Denial of Service (DoS) for applications utilizing the library.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
