JLSEC-2026-533

In OpenJPEG 2.3.1, there is excessive iteration in the opjt1encodecblks 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...

dnsmasq: NSEC bitmap parsing infinite loop

A denial of service vulnerability was discovered in dnsmasq's DNSSEC validation. When parsing NSEC and NSEC3 bitmap records, the window iteration logic fails to account for the 2-byte window header when advancing through the bitmap data. A specially crafted DNS response with a zero-length bitmap...

freerdp: FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId

A heap based buffer overflow flaw has been discovered in FreeRDP. This client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server can send a CACHEBITMAPORDER Rev1 with cacheId equal to maxCells,...
