Amazon Linux 2 : OpenEXR (ALAS-2020-1499)

medium Nessus Plugin ID 141952

Language:

Synopsis

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

Description

The version of OpenEXR installed on the remote host is prior to 1.7.1-8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1499 advisory.

 An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds read during Huffman uncompression, as demonstrated by FastHufDecoder::refill in ImfFastHuf.cpp. (CVE-2020-11761)

 An issue was discovered in OpenEXR before 2.4.1. There is an std::vector out-of-bounds read and write, as demonstrated by ImfTileOffsets.cpp. (CVE-2020-11763)

 An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds write in copyIntoFrameBuffer in ImfMisc.cpp. (CVE-2020-11764)

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

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

Solution

Run 'yum update OpenEXR' to update your system.
