An issue was discovered IW44EncodeCodec.cpp in djvulibre 3.5.28 in allows attackers to cause a denial of service via divide by zero.

An issue was discovered IW44Image.cpp in djvulibre 3.5.28 in allows attackers to cause a denial of service via divide by zero.

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.

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.

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.

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.

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.

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.

DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filter_fv at IW44EncodeCodec.cpp.

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.
