cups-browsed in cups-filters 1.0.41 before 1.0.51 allows remote IPP printers to execute arbitrary commands via shell metacharacters in the (1) model or (2) PDL, related to "System V interface scripts generated for queues."

cups-filters was updated to fix three security issues.

These security issues were fixed :

  - CVE-2015-2265: The remove_bad_chars function in     utils/cups-browsed.c in cups-filters before 1.0.66     allowed remote IPP printers to execute arbitrary     commands via consecutive shell metacharacters in the (1)     model or (2) PDL. NOTE: this vulnerability exists     because of an incomplete fix for CVE-2014-2707     (bsc#921753).

  - CVE-2015-3279: Texttopdf integer overflow (incomplete     fix for CVE-2015-3258) (bsc#937018).

  - CVE-2015-3258: Texttopdf heap-based buffer overflow     (bsc#936281).

Updated cups-filters packages fix security vulnerabilities :

Florian Weimer discovered that cups-filters incorrectly handled memory in the urftopdf filter. An attacker could possibly use this issue to execute arbitrary code with the privileges of the lp user (CVE-2013-6473).

Florian Weimer discovered that cups-filters incorrectly handled memory in the pdftoopvp filter. An attacker could possibly use this issue to execute arbitrary code with the privileges of the lp user (CVE-2013-6474, CVE-2013-6475).

Florian Weimer discovered that cups-filters did not restrict driver directories in in the pdftoopvp filter. An attacker could possibly use this issue to execute arbitrary code with the privileges of the lp user (CVE-2013-6476).

Sebastian Krahmer discovered it was possible to use malicious broadcast packets to execute arbitrary commands on a server running the cups-browsed daemon (CVE-2014-2707).

In cups-filters before 1.0.53, out-of-bounds accesses in the process_browse_data function when reading the packet variable could leading to a crash, thus resulting in a denial of service (CVE-2014-4337).

In cups-filters before 1.0.53, if there was only a single BrowseAllow line in cups-browsed.conf and its host specification was invalid, this was interpreted as if no BrowseAllow line had been specified, which resulted in it accepting browse packets from all hosts (CVE-2014-4338).

The CVE-2014-2707 issue with malicious broadcast packets, which had been fixed in Mageia Bug 13216 (MGASA-2014-0181), had not been completely fixed by that update. A more complete fix was implemented in cups-filters 1.0.53 (CVE-2014-4336).

Note that only systems that have enabled the affected feature by using the CreateIPPPrinterQueues configuration directive in /etc/cups/cups-browsed.conf were affected by the CVE-2014-2707 / CVE-2014-4336 issue.

The remote host is affected by the vulnerability described in GLSA-201406-16 (cups-filters: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in cups-filters. Please       review the CVE identifiers referenced below for more details about the       vulnerabilities.
  Impact :

    A remote attacker(s) could possibly execute arbitrary code utilizing       multiple attack vectors, or a local attacker could gain escalated       privileges via a specially crafted shared library.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2210-1 advisory.

    Sebastian Krahmer discovered that cups-browsed incorrectly filtered remote printer names and strings. A     remote attacker could use this issue to possibly execute arbitrary commands. (CVE-2014-2707)

    Johannes Meixner discovered that cups-browsed ignored invalid BrowseAllow directives. This could cause it     to accept browse packets from all hosts, contrary to intended configuration.
