Name of the Vulnerable Software and Affected Versions Exiv2 version 0.26

Description The issue is caused by an integer overflow in the LoaderExifJpeg class, leading to an out-of-bounds read. This can potentially allow a remote attacker to execute arbitrary code. The out-of-bounds read occurs in the Exiv2::MemIo::read function.

Recommendations For Exiv2 version 0.26, consider disabling the LoaderExifJpeg class in preview.cpp as a temporary workaround until a patch is available. Restrict access to the Exiv2::MemIo::read function in basicio.cpp to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
