lppasswd when running setuid or setgid still honors environment variables that specify the location of message files. Local attackers could exploit that to gather information by using crafted format strings (CVE-2010-0393).

The previous fix for a use-after-free vulnerability (CVE-2009-3553) was incomplete (CVE-2010-0302).

The remote host is running a version of Mac OS X 10.6.x that is prior to 10.6.3.

lppasswd when running setuid or setgid still honors environment variables that specify the location of message files. Local attackers could exploit that to gather information by using crafted format strings. (CVE-2010-0393)

The previous fix for a use-after-free vulnerability (CVE-2009-3553) was incomplete. (CVE-2010-0302)

The remote host is affected by the vulnerability described in GLSA-201207-10 (CUPS: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in CUPS. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker may be able to execute arbitrary code using specially       crafted streams, IPP requests or files, or cause a Denial of Service       (daemon crash or hang). A local attacker may be able to gain escalated       privileges or overwrite arbitrary files. Furthermore, a remote attacker       may be able to obtain sensitive information from the CUPS process or       hijack a CUPS administrator authentication request.
  Workaround :

    There is no known workaround at this time.

It was discovered that the CUPS scheduler did not properly handle certain network operations. A remote attacker could exploit this flaw and cause the CUPS server to crash, resulting in a denial of service.
This issue only affected Ubuntu 8.04 LTS, 8.10, 9.04 and 9.10.
(CVE-2009-3553, CVE-2010-0302)

Ronald Volgers discovered that the CUPS lppasswd tool could be made to load localized message strings from arbitrary files by setting an environment variable. A local attacker could exploit this with a format-string vulnerability leading to a root privilege escalation.
The default compiler options for Ubuntu 8.10, 9.04 and 9.10 should reduce this vulnerability to a denial of service. (CVE-2010-0393).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in cups :

CUPS in does not properly handle (1) HTTP headers and (2) HTML templates, which allows remote attackers to conduct cross-site scripting (XSS) attacks and HTTP response splitting attacks via vectors related to (a) the product's web interface, (b) the configuration of the print system, and (c) the titles of printed jobs (CVE-2009-2820).

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third-party information (CVE-2009-3553).

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7, 1.3.9, 1.3.10, and 1.4.1, when kqueue or epoll is used, allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third-party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-3553 (CVE-2010-0302).

The _cupsGetlang function, as used by lppasswd.c in lppasswd in CUPS 1.2.2, 1.3.7, 1.3.9, and 1.4.1, relies on an environment variable to determine the file that provides localized message strings, which allows local users to gain privileges via a file that contains crafted localization data with format string specifiers (CVE-2010-0393).

The updated packages have been patched to correct these issues.

Update :

Packages for Mandriva Linux 2010.0 was missing with MDVSA-2010:073.
This advisory provides packages for 2010.0 as well.

Ronald Volgers discovered that the lppasswd component of the cups suite, the Common UNIX Printing System, is vulnerable to format string attacks due to insecure use of the LOCALEDIR environment variable. An attacker can abuse this behaviour to execute arbitrary code via crafted localization files and triggering calls to _cupsLangprintf().
This works as the lppasswd binary happens to be installed with setuid 0 permissions.

According to its banner, the version of CUPS installed on the remote host is earlier than 1.4.3. Such versions are affected by several vulnerabilities :

  - A pointer use-after-free vulnerability exists in the     abstract file descriptor handling code in the     'cupsdDoSelect' function in scheduler/select.c. A remote     attacker may be able to leverage this to hang or crash     the cupsd daemon by disconnecting while receiving a     listing with a large number of print jobs. (STR #3200)

  - The lppasswd utility, when its setuid bit is enabled,     allowing a local user to elevaate privileges because it     uses an environment variable to override CUPS' default     directories and determine the location of a file with     localized message strings. (STR #3482)

The remote host is running a version of Mac OS X 10.5 that does not have Security Update 2010-002 applied.
