Weekly Vulnerabilities Reports > July 5 to 11, 2004

HelpViewer in Mac OS X 10.3.3 and 10.2.8 processes scripts that it did not initiate, which can allow attackers to execute arbitrary code, an issue that was originally reported as a directory traversal vulnerability in the Safari web browser using the runscript parameter in a help: URI handler.

BEA WebLogic Server and WebLogic Express 7.0 through SP5 and 8.1 through SP2, when editing weblogic.xml using WebLogic Builder or the SecurityRoleAssignmentMBean.toXML method, inadvertently removes security-role-assignment tags when weblogic.xml does not have a principal-name tag, which can remove intended access restrictions for the associated web application.

Stack-based buffer overflow in Exim 4 before 4.33, when the headers_check_syntax option is enabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code during the header check.

Stack-based buffer overflow in Exim 3.35, and other versions before 4, when the sender_verify option is true, allows remote attackers to cause a denial of service and possibly execute arbitrary code during sender verification.

Heap-based buffer overflow in the ne_rfc1036_parse date parsing function for the neon library (libneon) 0.24.5 and earlier, as used by cadaver before 0.22, allows remote WebDAV servers to execute arbitrary code on the client.

Stack-based buffer overflow during the apr_time_t data conversion in Subversion 1.0.2 and earlier allows remote attackers to execute arbitrary code via a (1) DAV2 REPORT query or (2) get-dated-rev svn-protocol command.

Integer overflow in the ip_setsockopt function in Linux kernel 2.4.22 through 2.4.25 and 2.6.1 through 2.6.3 allows local users to cause a denial of service (crash) or execute arbitrary code via the MCAST_MSFILTER socket option.

The showHelp function in Internet Explorer 6 on Windows XP Pro allows remote attackers to execute arbitrary local .CHM files via a double backward slash ("\\") before the target CHM file, as demonstrated using an "ms-its" URL to ntshared.chm.

Help Center (HelpCtr.exe) may allow remote attackers to read or execute arbitrary files via an "http://" or "file://" argument to the topic parameter in an hcp:// URL.

Integer overflow in Apple QuickTime (QuickTime.qts) before 6.5.1 allows attackers to execute arbitrary code via a large "number of entries" field in the sample-to-chunk table data for a .mov movie file, which leads to a heap-based buffer overflow.

Stack-based buffer overflow in AppleFileServer for Mac OS X 10.3.3 and earlier allows remote attackers to execute arbitrary code via a LoginExt packet for a Cleartext Password User Authentication Method (UAM) request with a PathName argument that includes an AFPName type string that is longer than the associated length field.

The default protocol helper for the disk: URI on Mac OS X 10.3.3 and 10.2.8 allows remote attackers to write arbitrary files by causing a disk image file (.dmg) to be mounted as a disk volume.

Unknown vulnerability in rpc.mountd for SGI IRIX 6.5.24 allows remote attackers to cause a denial of service (infinite loop) via certain RPC requests.

Internet Explorer 6 allows remote attackers to cause a denial of service (crash) via Javascript that creates a new popup window and disables the imagetoolbar functionality with a META tag, which triggers a null dereference.

The Clear Channel Assessment (CCA) algorithm in the IEEE 802.11 wireless protocol, when using DSSS transmission encoding, allows remote attackers to cause a denial of service via a certain RF signal that causes a channel to appear busy (aka "jabber"), which prevents devices from transmitting data.

Titan FTP Server version 3.01 build 163, and possibly other versions before build 169, allows remote authenticated users to cause a denial of service (crash) by disconnecting from the system during a "LIST -L" command, which causes Titan to access an invalid socket.

rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot, which allows remote attackers to write files outside of the module's path.

Buffer overflow in xpcd-svga in xpcd before 2.08, and possibly other versions, may allow local users to execute arbitrary code.

mshtml.dll in Microsoft Internet Explorer 6.0.2800 allows remote attackers to cause a denial of service (crash) via a table containing a form that crosses multiple td elements, and whose "float: left" class is defined in a link to a CSS stylesheet after the end of the table, which may trigger a null dereference.

Unknown versions of Mozilla allow remote attackers to cause a denial of service (high CPU/RAM consumption) using Javascript with an infinite loop that continues to add input to a form, possibly as the result of inserting control characters, as demonstrated using an embedded ctrl-U.

Argument injection vulnerability in Opera before 7.50 does not properly filter "-" characters that begin a hostname in a telnet URI, which allows remote attackers to insert options to the resulting command line and overwrite arbitrary files via (1) the "-f" option on Windows XP or (2) the "-n" option on Linux.

The SYMDNS.SYS driver in Symantec Norton Internet Security and Professional 2002 through 2004, Norton Personal Firewall 2002 through 2004, Norton AntiSpam 2004, Client Firewall 5.01 and 5.1.1, and Client Security 1.0 through 2.0 allows remote attackers to cause a denial of service (CPU consumption from infinite loop) via a DNS response with a compressed name pointer that points to itself.

BEA WebLogic Server and WebLogic Express 7.0 through SP5 and 8.1 through SP2 does not enforce site restrictions for starting and stopping servers for users in the Admin and Operator security roles, which allows unauthorized users to cause a denial of service (service shutdown).

The log_event function in ssmtp 2.50.6 and earlier allows local users to overwrite arbitrary files via a symlink attack on the ssmtp.log temporary log file.

flim before 1.14.3 creates temporary files insecurely, which allows local users to overwrite arbitrary files of the Emacs user via a symlink attack.

logcheck before 1.1.1 allows local users to overwrite arbitrary files via a symlink attack on a temporary directory in /var/tmp.
