Amazon Linux 2 : exiv2 (ALAS-2021-1701)

high Nessus Plugin ID 153421

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of exiv2 installed on the remote host is prior to 0.27.0-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1701 advisory.

 A flaw was found in exiv2. A flawed bounds checking in the jp2Image.cpp:doWriteMetadata function leads to a heap-based buffer overflow. This flaw allows an attacker who can provide a malicious image to an application using the exiv2 library, to write data out of bounds and potentially execute code. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
 (CVE-2021-31291)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update exiv2' to update your system.
