"The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:3543-1 advisory.
- Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
of image files. An inefficient algorithm (quadratic complexity) was found in Exiv2 versions v0.27.3 and
earlier. The inefficient algorithm is triggered when Exiv2 is used to write metadata into a crafted image
file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can
trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.4. Note
that this bug is only triggered when _writing_ the metadata, which is a less frequently used Exiv2
operation than _reading_ the metadata. For example, to trigger the bug in the Exiv2 command-line
application, you need to add an extra command-line argument such as `rm`. (CVE-2021-32617)
