Ethereal 0.10.3 allows remote attackers to cause a denial of service (crash) via certain SIP messages between Hotsip servers and clients.
The HTTP dissector in Ethereal 0.10.1 through 0.10.7 allows remote attackers to cause a denial of service (application crash) via a certain packet that causes the dissector to access previously-freed memory.
Ethereal 0.9.0 through 0.10.7 allows remote attackers to cause a denial of service (application hang) and possibly fill available disk space via an invalid RTP timestamp.
The SNMP dissector in Ethereal 0.8.15 through 0.10.4 allows remote attackers to cause a denial of service (process crash) via a (1) malformed or (2) missing community string, which causes an out-of-bounds read.
The iSNS dissector for Ethereal 0.10.3 through 0.10.4 allows remote attackers to cause a denial of service (process abort) via an integer overflow.
The SMB SID snooping capability in Ethereal 0.9.15 to 0.10.4 allows remote attackers to cause a denial of service (process crash) via a handle without a policy name, which causes a null dereference.
Ethereal 0.10.1 to 0.10.2 allows remote attackers to cause a denial of service (crash) via a zero-length Presentation protocol selector.
The AIM dissector in Ethereal 0.10.3 allows remote attackers to cause a denial of service (assert error) via unknown attack vectors.
The SPNEGO dissector in Ethereal 0.9.8 to 0.10.3 allows remote attackers to cause a denial of service (crash) via unknown attack vectors that cause a null pointer dereference.
Multiple buffer overflows in Ethereal 0.8.13 to 0.10.2 allow remote attackers to cause a denial of service and possibly execute arbitrary code via the (1) NetFlow, (2) IGAP, (3) EIGRP, (4) PGM, (5) IrDA, (6) BGP, (7) ISUP, or (8) TCAP dissectors.
Ethereal 0.9.15 and earlier, and Tethereal, allows remote attackers to cause a denial of service (crash) via certain malformed (1) ISAKMP or (2) MEGACO packets.
The SPNEGO dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (crash) via an invalid ASN.1 value.
Unknown vulnerability in the DCERPC (DCE/RPC) dissector in Ethereal 0.9.12 and earlier allows remote attackers to cause a denial of service (memory consumption) via a certain NDR string.
DNS dissector in Ethereal before 0.9.3 allows remote attackers to cause a denial of service (CPU consumption) via a malformed packet that causes Ethereal to enter an infinite loop.
The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a certain malformed packet, which causes Ethereal to allocate memory incorrectly, possibly due to zero-length fields.
Multiple unspecified vulnerabilities in Ethereal 0.10.x up to 0.10.14 allow remote attackers to cause a denial of service (crash from null dereference) via (1) multiple vectors in H.248, and the (2) X.509if, (3) SRVLOC, (4) H.245, (5) AIM, and (6) general packet dissectors; and (7) the statistics counter.
