OpenJPEG 2.4.0 through 2.5.4, and git master through commit 8314119b, contains an out-of-bounds read and write in opj_dwt_encode_and_deinterleave_v() in src/lib/openjp2/dwt.c. This allows an attacker to cause a denial of service.
A vulnerability was identified in uclouvain openjpeg up to 2.5.4. This impacts the function opj_pi_initialise_encode in the library src/lib/openjp2/pi.c. The manipulation leads to integer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is 839936aa33eb8899bbbd80fda02796bb65068951. It is suggested to install a patch to address this issue.
openjpeg v 2.5.0 was discovered to contain a NULL pointer dereference via the component /openjp2/dwt.c.
A flaw was found in the OpenJPEG project. A heap buffer overflow condition may be triggered when certain options are specified while using the opj_decompress utility. This can lead to an application crash or other undefined behavior.

A flaw was found in OpenJPEG. A resource exhaustion can occur in the opj_t1_decode_cblks function in tcd.c through a crafted image file, causing a denial of service.
A flaw was found in OpenJPEG. Maliciously constructed pictures can cause the program to enter a large loop and continuously print warning messages on the terminal.
A vulnerability was found in OpenJPEG similar to CVE-2019-6988. This flaw allows an attacker to bypass existing protections and cause an application crash through a maliciously crafted file.
A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.
A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.
Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when the attacker uses the command line option "-ImgDir" on a directory that contains 1048576 files.
A flaw was found in OpenJPEG in versions prior to 2.4.0. This flaw allows an attacker to provide specially crafted input to the conversion or encoding functionality, causing an out-of-bounds read. The highest threat from this vulnerability is system availability.
In OpenJPEG 2.3.1, there is excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file. This issue is similar to CVE-2018-6616.
Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application crash).
An issue was discovered in OpenJPEG 2.3.0. It allows remote attackers to cause a denial of service (attempted excessive memory allocation) in opj_calloc in openjp2/opj_malloc.c, when called from opj_tcd_init_tile in openjp2/tcd.c, as demonstrated by the 64-bit opj_decompress.
An issue was discovered in OpenJPEG 2.3.0. Missing checks for header_info.height and header_info.width in the function pnmtoimage in bin/jpwl/convert.c can lead to a heap-based buffer overflow.
In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
