Weekly Vulnerabilities Reports > May 23 to 29, 2011

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field.

The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.

SQL injection vulnerability in RADVISION iVIEW Suite before 7.5 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

Google Chrome OS before R12 0.12.433.38 Beta allows local users to gain privileges by creating a /var/lib/chromeos-aliases.conf file and placing commands in it.

The STARTTLS implementation in WatchGuard XCS 9.0 and 9.1 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

script-login in Dovecot 2.0.x before 2.0.13 does not follow the chroot configuration setting, which might allow remote authenticated users to conduct directory traversal attacks by leveraging a script.

script-login in Dovecot 2.0.x before 2.0.13 does not follow the user and group configuration settings, which might allow remote authenticated users to bypass intended access restrictions by leveraging a script.

The urllib and urllib2 modules in Python 2.x before 2.7.2 and 3.x before 3.2.1 process Location headers that specify redirection to file: URLs, which makes it easier for remote attackers to obtain sensitive information or cause a denial of service (resource consumption) via a crafted URL, as demonstrated by the file:///etc/passwd and file:///dev/zero URLs.

includes/User.php in MediaWiki before 1.16.5, when wgBlockDisablesLogin is enabled, does not clear certain cached data after verification of an auth token fails, which allows remote attackers to bypass authentication by creating crafted wikiUserID and wikiUserName cookies, or by leveraging an unattended workstation.

The STARTTLS implementation in ftp_parser.c in Pure-FTPd before 1.0.30 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted FTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

feh before 1.8, when the --wget-timestamp option is enabled, might allow remote attackers to execute arbitrary commands via shell metacharacters in a URL.

The STARTTLS implementation in Cyrus IMAP Server before 2.4.7 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message.

Google Chrome OS before R12 0.12.433.38 Beta, when Guest mode is enabled, does not prevent changes on the about:flags page, which has unspecified impact and local attack vectors.

Cross-site scripting (XSS) vulnerability in the search center in IBM WebSphere Portal 7.0.0.1 before CF004 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Directory traversal vulnerability in the disk_create function in disk.c in rdesktop before 1.7.0, when disk redirection is enabled, allows remote RDP servers to read or overwrite arbitrary files via a ..

The implementation of OutputMediator objects in IBM WebSphere Portal 6.0.1.7, and 7.0.0.1 before CF002, allows remote authenticated users to cause a denial of service (memory consumption) via requests.

The authoring tool in IBM Web Content Manager (WCM) 6.1.5, and 7.0.0.1 before CF003, allows remote authenticated users to bypass intended access restrictions on draft creation by leveraging certain resource editor privileges.

The glob implementation in Pure-FTPd before 1.0.32, and in libc in NetBSD 5.1, does not properly expand expressions containing curly brackets, which allows remote authenticated users to cause a denial of service (memory consumption) via a crafted FTP STAT command.

Race condition in IBM Web Content Manager (WCM) 7.0.0.1 before CF003 allows remote authenticated users to cause a denial of service (infinite recursive query) via unspecified vectors, related to a StackOverflowError exception.

The default configuration of ExShortcut\Web.config in EMC SourceOne Email Management before 6.6 SP1, when the Mobile Services component is used, does not properly set the localOnly attribute of the trace element, which allows remote authenticated users to obtain sensitive information via ASP.NET Application Tracing.

The make include files in NetBSD before 1.6.2, as used in pmake 1.111 and other products, allow local users to overwrite arbitrary files via a symlink attack on a /tmp/_depend##### temporary file, related to (1) bsd.lib.mk and (2) bsd.prog.mk.
