Synopsis

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

Description

The remote SUSE Linux SLED12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2913-1 advisory.

 - 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 hufUncompress functionality in OpenEXR/IlmImf/ImfHuf.cpp. This flaw allows an attacker who can submit a crafted file that is processed by OpenEXR, to trigger an integer overflow.
 The highest threat from this vulnerability is to system availability. (CVE-2021-20300)

 - A flaw was found in OpenEXR's TiledInputFile functionality. This flaw allows an attacker who can submit a crafted single-part non-image to be processed by OpenEXR, to trigger a floating-point exception error. The highest threat from this vulnerability is to system availability. (CVE-2021-20302)

 - 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 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)

 - A flaw was found in OpenEXR's B44 uncompression functionality in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to OpenEXR could trigger shift overflows, potentially affecting application availability. (CVE-2021-3476)

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

Solution

Update the affected libIlmImf-Imf_2_1-21, libIlmImf-Imf_2_1-21-32bit, openexr and / or openexr-devel packages.
