Multiple heap-based buffer overflows in Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allow remote attackers to cause a denial of service (application crash) or execute arbitrary code via (1) the "Send page" functionality, (2) certain responses from a malicious POP3 server, or (3) a link containing a non-ASCII hostname.

Stack-based buffer overflow in the writeGroup function in nsVCardObj.cpp for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to execute arbitrary code via malformed VCard attachments that are not properly handled when previewing a message.

The EPSF pipe support in enscript 1.6.3 allows remote attackers or local users to execute arbitrary commands via shell metacharacters.

Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to perform cross-domain scripting and possibly execute arbitrary code by convincing a user to drag and drop javascript: links to a frame or page in another domain.

SuSEconfig.javarunt in the javarunt package on SuSE Linux 7.3Pro allows local users to overwrite arbitrary files via a symlink attack on the .java_wrapper temporary file.

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

runlpr in the LPRng package allows the local lp user to gain root privileges via certain command line arguments.

Buffer overflows in ISDN Point to Point Protocol (PPP) daemon (ipppd) in the i4l package on SuSE 7.3, 8.0, and possibly other operating systems, may allow local users to gain privileges.

Buffer overflow in lukemftp FTP client in SuSE 6.4 through 8.0, and possibly other operating systems, allows a malicious FTP server to execute arbitrary code via a long PASV command.
