CVE-2007-5030
Multiple integer overflows in Dibbler 0.6.0 allow remote attackers to cause a denial of service (daemon crash) via packets containing options with large lengths, which trigger attempts at excessive memory allocation, as demonstrated by (1) the TSrvMsg constructor in SrvMessages/SrvMsg.cpp; the (2) TClntMsg, (3) TClntOptIAAddress, (4) TClntOptIAPrefix, (5) TOptVendorSpecInfo, and (6) TOptOptionRequest constructors; and the (7) TRelIfaceMgr::decodeRelayRepl, (8) TRelMsg::decodeOpts, and (9) TSrvIfaceMgr::decodeRelayForw methods.
CVE-2007-5031
The TSrvOptIA_NA::rebind method in SrvOptions/SrvOptIA_NA.cpp in Dibbler 0.6.0 allows remote attackers to cause a denial of service (NULL dereference and daemon crash) via an invalid IA_NA option in a REBIND message.
CVE-2007-5028
Dibbler 0.6.0 on Linux uses weak world-writable permissions for unspecified files in /var/lib/dibbler, which has unknown impact and local attack vectors.
CVE-2007-5029
Dibbler 0.6.0 does not verify that certain length parameters are appropriate for buffer sizes, which allows remote attackers to trigger a buffer over-read and cause a denial of service (daemon crash), as demonstrated by incorrect behavior of the TSrvMsg constructor in SrvMessages/SrvMsg.cpp when (1) reading the option code and option length and (2) parsing options.
