CVE-2026-13002 Dnsmasq: infinite loop dos in dnssec nsec/nsec3 type bitmap parsing

A flow has been identified into dnssec.c library, causing an infinite loop to dnsmasq service. An attacker who controls any DNSSEC-signed zone can hang the dnsmasq process with a single crafted response, killing all DNS resolution for its clients...

FreeRDP: FreeRDP: Remote code execution via heap out-of-bounds write in RemoteFX decoding

A flaw was found in FreeRDP. FreeRDP clients using the non-default /cache:codec:rfx option are vulnerable to a heap out-of-bounds write. A malicious Remote Desktop Protocol RDP server can exploit this by manipulating desktop stride and height values during RemoteFX decoding for Cache Bitmap V3...

CVE-2026-42500

A flaw was found in golang.org/x/image/bmp. A remote attacker could exploit this vulnerability by providing a specially crafted paletted BMP Bitmap file. Decoding this file with an out-of-range palette index causes the application to panic when accessing invalid image pixels, leading to a Denial ...
