Ubuntu 20.04 LTS : OpenJPEG vulnerabilities (USN-4685-1)

high Nessus Plugin ID 144788

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 20.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4685-1 advisory.

 - jp2/opj_decompress.c in OpenJPEG through 2.3.1 has a use-after-free that can be triggered if there is a mix of valid and invalid files in a directory operated on by the decompressor. Triggering a double-free may also be possible. This is related to calling opj_image_destroy twice. (CVE-2020-15389)

 - There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability. (CVE-2020-27841)

 - There's a flaw in openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of this flaw is to application availability. (CVE-2020-27842)

 - A flaw was found in OpenJPEG in versions prior to 2.4.0. This flaw allows an attacker to provide specially crafted input to the conversion or encoding functionality, causing an out-of-bounds read. The highest threat from this vulnerability is system availability. (CVE-2020-27843)

 - There's a flaw in src/lib/openjp2/pi.c of openjpeg in versions prior to 2.4.0. If an attacker is able to provide untrusted input to openjpeg's conversion/encoding functionality, they could cause an out-of-bounds read. The highest impact of this flaw is to application availability. (CVE-2020-27845)

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