EulerOS 2.0 SP8 : OpenEXR (EulerOS-SA-2021-2477)

medium Nessus Plugin ID 153658

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the OpenEXR package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A flaw found in function dataWindowForTile() of IlmImf/ImfTiledMisc.cpp. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, leading to an out-of-bounds write on the heap. The greatest impact of this flaw is to application availability, with some potential impact to data integrity as well. (CVE-2021-20303)

- A flaw was found in OpenEXR's B44Compressor. This flaw allows an attacker who can submit a crafted file to be processed by OpenEXR, to exhaust all memory accessible to the application. The highest threat from this vulnerability is to system availability. (CVE-2021-20298)

- A flaw was found in OpenEXR's Multipart input file functionality. A crafted multi-part input file with no actual parts can trigger a NULL pointer dereference. The highest threat from this vulnerability is to system availability. (CVE-2021-20299)

- A flaw was found in OpenEXR's hufDecode functionality. This flaw allows an attacker who can pass a crafted file to be processed by OpenEXR, to trigger an undefined right shift error. The highest threat from this vulnerability is to system availability. (CVE-2021-20304)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected OpenEXR packages.
