Hi, * Thomas Sader <thommey () gmail com> [2009-05-15 11:52]:
Affected software ----------------- eggdrop (1.6.19 only, not 1.6.19+ctcpfix) windrop (1.6.19 only, not 1.6.19+ctcpfix) all eggdrop/windrop versions and packages which apply Nico Goldes patch for CVE-2007-2807/SA25276 See: [1] Vulnerability details --------------------- The SA25276 patch ([1]) uses strncpy to fix a buffer overflow vulnerability in src/mod/server.mod/servmsg.c (gotmsg). The last argument is not checked for being non-negative, but that can happen if ctcpbuf is "". That causes a remote crash vulnerability to be exploited by anyone connected to the same IRC network as eggdrop. The SA25276 patch has been applied to the eggdrop1.6.18 debian package and was later adopted by Eggheads into eggdrop1.6.19.
