GreycLab CImg through 4.0.6 Heap Out-of-Bounds Read via Integer Overflow in _load_bmp()

CImg through 4.0.6 contains a heap out-of-bounds read vulnerability in the _load_bmp() function of CImg.h caused by an integer overflow in the row byte count. Attackers can supply a crafted BMP file with a large header width that wraps dx_bytes, causing crashes or heap memory disclosure into the decoded image.

A heap-based buffer overflow in Clmg before 3.3.3 can occur via a crafted file to cimg_library::CImg<unsigned char>::_load_analyze.

An issue in cimg.eu Cimg Library v2.9.3 allows an attacker to obtain sensitive information via a crafted JPEG file.

A flaw was found in Clmg, where with the help of a maliciously crafted pandore or bmp file with modified dx and dy header field values it is possible to trick the application into allocating huge buffer sizes like 64 Gigabyte upon reading the file from disk or from a virtual buffer.

A flaw was found in CImg in versions prior to 2.9.3. Integer overflows leading to heap buffer overflows in load_pnm() can be triggered by a specially crafted input file processed by CImg, which can lead to an impact to application availability or data integrity.

CImg through 2.6.7 has a heap-based buffer overflow in _load_bmp in CImg.h because of erroneous memory allocation for a malformed BMP image.

CImg The CImg Library v.2.3.3 and earlier is affected by: command injection. The impact is: RCE. The component is: load_network() function. The attack vector is: Loading an image from a user-controllable url can lead to command injection, because no string sanitization is done on the url. The fixed version is: v.2.3.4.

An issue was discovered in CImg v.220. A heap-based buffer over-read in load_bmp in CImg.h occurs when loading a crafted bmp image, a different vulnerability than CVE-2018-7588. This is in a "32 bits colors" case, aka case 32.
