Candidate: CVE-2006-4623 References: http://lkml.org/lkml/2006/8/20/278 Description: The Unidirectional Lightweight Encapsulation (ULE) decapsulation component in dvb-core/dvb_net.c in the dvb driver in the Linux kernel 2.6.17.8 allows remote attackers to cause a denial of service (crash) via an SNDU length of 0 in a ULE packet. Ubuntu-Description: A flaw was discovered in dvb ULE decapsulation. A remote attacker could send a specially crafted message and cause a denial of service. Notes: mpitt> Questionable -- rather than fixing the kernel to not send out invalid ULE packets, it should be fixed to not crash upon receiving one. dannf> I noticed that a different, and much larger patch went into 2.6.18 that conflicts with the one provided by the original reporter (which went into 2.6.17.y). I asked the original reporter if that patch also fixed the issue. Ang Way replied: "Yes, it is fixed in 2.6.18 and later even though the patch is different. Their fix is more elegant."
