CVE-2007-4643Date: (C)2007-08-31   (M)2018-02-19


Integer underflow in Doomsday (aka deng) 1.9.0-beta5.1 and earlier allows remote attackers to cause a denial of service (daemon crash) via a PKT_CHAT packet with a data length less than 3, which triggers an erroneous malloc, possibly related to the Sv_HandlePacket function in sv_main.c.
