Alpine: multiple exiv2 packages: security update to 0.27.3-r1
high Tenable Cloud Security Plugin ID 404257
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A flaw was found in Exiv2 in versions before and including 0.27.4-RC1. Improper input validation of the
rawData.size property in Jp2Image::readMetadata() in jp2image.cpp can lead to a heap-based buffer overflow
via a crafted JPG image containing malicious EXIF data. (CVE-2021-3482)
- Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
of image files. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. 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 `insert`. The bug is
fixed in version v0.27.4. (CVE-2021-29457)
- 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 versions v0.27.3 and earlier. The out-of-bounds
read 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 by crashing Exiv2, 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 insert. The bug is fixed in version v0.27.4. (CVE-2021-29458)
