The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3755-1 advisory.
A flaw was found in djvulibre-3.5.28 and earlier. An out of bounds write in function DJVU::filter_bv() via crafted djvu file may lead to application crash and other consequences. (CVE-2021-32490)
An issue was discovered IW44Image.cpp in djvulibre 3.5.28 in allows attackers to cause a denial of service via divide by zero. (CVE-2021-46310)
An issue was discovered IW44EncodeCodec.cpp in djvulibre 3.5.28 in allows attackers to cause a denial of service via divide by zero. (CVE-2021-46312)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
