CVE-2025-26623:
Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A heap buffer overflow was found in Exiv2 versions v0.28.0 to v0.28.4. Versions prior to v0.28.0, such as v0.27.7, are **not** affected. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The heap overflow is triggered when Exiv2 is used to write metadata into 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. 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 `fixiso`. The bug is fixed in version v0.28.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.
Among the 4 debian patches
available in version 0.28.4+dfsg-2 of the package,
we noticed the following issues:
2 patches
where the metadata indicates that the patch has not yet been forwarded
upstream. You should either forward the patch upstream or update the
metadata to document its real status.
CVE-2024-24826:
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 version v0.28.1. The vulnerable function, `QuickTimeVideo::NikonTagsDecoder`, was new in v0.28.0, so Exiv2 versions before v0.28 are _not_ affected. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file. In most cases this out of bounds read will result in a crash. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2024-25112:
Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A denial-of-service was found in Exiv2 version v0.28.1: an unbounded recursion can cause Exiv2 to crash by exhausting the stack. The vulnerable function, `QuickTimeVideo::multipleEntriesDecoder`, was new in v0.28.0, so Exiv2 versions before v0.28 are _not_ affected. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted video file. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.
