A malicious user could precreate a symlink, pointing to the file /tmp/eglog, Subsequent run of the '/sbin/egenera' command would destroy / truncate the target of this link to zero length.

The fence_apc and fence_apc_snmp programs, as used in fence 2.02.00-r1 and possibly cman, when running in verbose mode, allows local users to append to arbitrary files via a symlink attack on the apclog temporary file.

A flaw was found in the way Adobe Flash Player wrote content to the clipboard. A malicious SWF file could populate the clipboard with a URL that could cause the user to mistakenly load an attacker-controlled URL. (CVE-2008-3873)

A flaw was found which allowed Adobe Flash Player's ActionScript to initiate file uploads and downloads without user interaction. FileReference.browse and FileReference.download calls can now only be initiated via user interaction, such as mouse-clicks or key-presses on the keyboard. (CVE-2008-4401)

A flaw was found in Adobe Flash Player's display of the Settings Manager content. A malicious SWF file could trick the user into unknowingly clicking a link or dialog. This could then give the malicious SWF file permission to access the local machine's camera or microphone. (CVE-2008-4503)

Miklos Szeredi reported that splice() to files opened with O_APPEND are ignored, which allows users to bypass the append-only restriction.

The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247.

From the SUSE advisory:

CVE-2008-3911: The proc_do_xprt function in net/sunrpc/sysctl.c in the Linux kernel 2.6.26.3 does not check the length of a certain buffer obtained from user space, which allows local users to overflow a stack-based buffer and have unspecified other impact via a crafted read system call for the /proc/sys/sunrpc/transports file.

CVE-2008-4618: Fixed a kernel panic in SCTP while process protocol violation parameter.

From the Fedora advisory:

Another bugfix release for the 3.1 series is out. This fixes several bugs : * A crash caused by a SIGBUS, when diskspace preallocation is disabled * High CPU usage when DNS lookups fail in the UDP tracker code * Several security issues in the webinterface plugin

From the Red Hat advisory:

An arbitrary command execution flaw was found in the Lynx "lynxcgi:" URI handler. An attacker could create a web page redirecting to a malicious URL that could execute arbitrary code as the user running Lynx in the non-default "Advanced" user mode. (CVE-2008-4690)

A flaw was found in a way Lynx handled ".mailcap" and ".mime.types" configuration files. Files in the browser's current working directory were opened before those in the user's home directory. A local attacker, able to convince a user to run Lynx in a directory under their control, could possibly execute arbitrary commands as the user running Lynx. (CVE-2006-7234)

Squirrelmail 1.4.15 does not set the secure flag for the session cookie in an https session, which can cause the cookie to be sent in http requests and make it easier for remote attackers to capture this cookie.

From the CVE entries:

CVE-2008-4680: packet-usb.c in the USB dissector in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via a malformed USB Request Block (URB).

CVE-2008-4681: Unspecified vulnerability in the Bluetooth RFCOMM dissector in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via unknown packets.

CVE-2008-4682: wtap.c in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application abort) via a malformed Tamos CommView capture file (aka .ncf file) with an "unknown/unexpected packet type" that triggers a failed assertion.

CVE-2008-4683: The dissect_btacl function in packet-bthci_acl.c in the Bluetooth ACL dissector in Wireshark 0.99.2 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via a packet with an invalid length, related to an erroneous tvb_memcpy call.

CVE-2008-4684: packet-frame in Wireshark 0.99.2 through 1.0.3 does not properly handle exceptions thrown by post dissectors, which allows remote attackers to cause a denial of service (application crash) via a certain series of packets, as demonstrated by enabling the (1) PRP or (2) MATE post dissector.

CVE-2008-4685: Use-after-free vulnerability in the dissect_q931_cause_ie function in packet-q931.c in the Q.931 dissector in Wireshark 0.10.3 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via certain packets that trigger an exception.
