Security issues fixed :

CVE-2021-32491 [bsc#1185900]: Integer overflow in function render() in tools/ddjvu via crafted djvu file

CVE-2021-32492 [bsc#1185904]: Out of bounds read in function DJVU:DataPool:has_data() via crafted djvu file

CVE-2021-32493 [bsc#1185905]: Heap buffer overflow in function DJVU:GBitmap:decode() via crafted djvu file

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4198-1 advisory.

    It was discovered that DjVuLibre incorrectly handled certain memory operations. If a user or automated     system were tricked into processing a specially crafted DjVu file, a remote attacker could cause     applications to hang or crash, resulting in a denial of service, or possibly execute arbitrary code.

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

Several vulnerabilities were discovered in djvulibre, a library and set of tools to handle documents in the DjVu format. An attacker could crash document viewers and possibly execute arbitrary code through crafted DjVu files.

For Debian 9 stretch, these problems have been fixed in version 3.5.27.1-7+deb9u1.

We recommend that you upgrade your djvulibre packages.

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5032 advisory.

  - In DjVuLibre 3.5.27, DjVmDir.cpp in the DJVU reader component allows attackers to cause a denial-of-     service (application crash in GStringRep::strdup in libdjvu/GString.cpp caused by a heap-based buffer     over-read) by crafting a DJVU file. (CVE-2019-15142)

  - In DjVuLibre 3.5.27, the bitmap reader component allows attackers to cause a denial-of-service error     (resource exhaustion caused by a GBitmap::read_rle_raw infinite loop) by crafting a corrupted image file,     related to libdjvu/DjVmDir.cpp and libdjvu/GBitmap.cpp. (CVE-2019-15143)

  - In DjVuLibre 3.5.27, the sorting functionality (aka GArrayTemplate<TYPE>::sort) allows attackers to cause     a denial-of-service (application crash due to an Uncontrolled Recursion) by crafting a PBM image file that     is mishandled in libdjvu/GContainer.h. (CVE-2019-15144)

  - DjVuLibre 3.5.27 allows attackers to cause a denial-of-service attack (application crash via an out-of-     bounds read) by crafting a corrupted JB2 image file that is mishandled in     JB2Dict::JB2Codec::get_direct_context in libdjvu/JB2Image.h because of a missing zero-bytes check in     libdjvu/GBitmap.h. (CVE-2019-15145)

  - DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filter_fv at IW44EncodeCodec.cpp.
    (CVE-2019-18804)

  - 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)

  - A flaw was found in djvulibre-3.5.28 and earlier. An integer overflow in function render() in tools/ddjvu     via crafted djvu file may lead to application crash and other consequences. (CVE-2021-32491)

  - A flaw was found in djvulibre-3.5.28 and earlier. An out of bounds read in function     DJVU::DataPool::has_data() via crafted djvu file may lead to application crash and other consequences.
    (CVE-2021-32492)

  - A flaw was found in djvulibre-3.5.28 and earlier. A heap buffer overflow in function     DJVU::GBitmap::decode() via crafted djvu file may lead to application crash and other consequences.
    (CVE-2021-32493)

  - A flaw was found in djvulibre-3.5.28 and earlier. A Stack overflow in function     DJVU::DjVuDocument::get_djvu_file() via crafted djvu file may lead to application crash and other     consequences. (CVE-2021-3500)

  - An out-of-bounds write vulnerability was found in DjVuLibre in DJVU::DjVuTXT::decode() in DjVuText.cpp via     a crafted djvu file which may lead to crash and segmentation fault. This flaw affects DjVuLibre versions     prior to 3.5.28. (CVE-2021-3630)

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

It was discovered that there was a NULL pointer dereference issue in the IW44 encoder/decoder within DjVu, a set of compression technologies for high-resolution ssues.

For Debian 8 'Jessie', this issue has been fixed in djvulibre version 3.5.25.4-4+deb8u2.

We recommend that you upgrade your djvulibre packages.
