EUVD-2026-31898

FastNetMon Community Edition through 1.2.9 contains an integer overflow in the BGP ASPATH attribute encoder. In src/bgpprotocol.hpp, the IPv4UnicastAnnounce::getattributes function computes attributelength as 'sizeofbgpaspathsegmentelementt + this-aspathasns.size sizeofuint32t' and stores it in a...

CVE-2026-48689

FastNetMon Community Edition through 1.2.9 contains an off-by-one heap-based buffer overflow in the dynamicbinarybuffert class src/dynamicbinarybuffer.hpp. Five methods appenddynamicbuffer, appenddataaspointer, appenddataasobjectptr, memcpyfromptr, memcpyfromobjectptr use an incorrect bounds chec...
