CVE-2026-42146 CImg Library: Uncontrolled memory allocation via nb_colors field in _load_bmp

CImg Library is a C++ library for image processing. Prior to commit c3aacf5, the nbcolors field read from the BMP file header is used directly to compute an allocation size without validating it against the remaining file size. A crafted BMP file with a large nbcolors value triggers an...

EUVD-2026-27075

CImg Library is a C++ library for image processing. Prior to commit 4ca26bc, there is an integer overflow vulnerability in the WHD size computation inside loadpnm that can bypass the memory allocation guard. A crafted PNM/PGM/PPM file with large dimension values causes the overflow to wrap around...

CVE-2026-40466

A flaw was found in Apache ActiveMQ. An authenticated attacker can bypass a previous security fix by adding a connector using an HTTP Discovery transport through Jolokia, if the activemq-http module is present. A malicious HTTP endpoint can return a virtual machine VM transport, which allows the...
