Description SMASH SMASH 2023-11-07 04:02:26 UTC

Exiv2 is a C++ library and a command-line utility to read, write, delete and
modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds wction BmffImage:brotliUncompressrite was found
in Exiv2 version v0.28.0. The vulnerable function,
`BmffImage::brotliUncompress`, is new in v0.28.0, so earlier versions of Exiv2
are _not_ affected. The out-of-bounds write is triggered when Exiv2 is used to
read the metadata of a crafted image file. An attacker could potentially exploit
the vulnerability to gain code execution, if they can trick the victim into
running Exiv2 on a crafted image file. This bug is fixed in version v0.28.1.
Users are advised to upgrade. There are no known workarounds for this
vulnerability.
