CUPS: buffer overflow of texttopdf
Synthesis of the vulnerability
An attacker can generate a buffer overflow in texttopdf of CUPS, in order to trigger a denial of service, and possibly to execute code.
Impacted products: CUPS, Debian, Fedora, openSUSE, RHEL, Ubuntu.
Severity: 2/4.
Consequences: privileged access/rights, denial of service on server, denial of service on service.
Provenance: user account.
Number of vulnerabilities in this bulletin: 2.
Creation date: 29/06/2015.
Identifiers: 1235385, CVE-2015-3258, CVE-2015-3279, DSA-3303-1, FEDORA-2015-11163, FEDORA-2015-11192, openSUSE-SU-2015:1244-1, RHSA-2015:2360-01, USN-2659-1, VIGILANCE-VUL-17249.
Description of the vulnerability
The CUPS product includes a tool to convert raw text to PDF.
When generating the PDF header, in the function "WriteProlog", a buffer size is computed from the number of lines and columns of text. However, if the specified size is too small, an invalid buffer size is used and an overflow will happen when generating pages.
An attacker can therefore generate a buffer overflow in texttopdf of CUPS, in order to trigger a denial of service, and possibly to execute code.

CUPS: endless loop in the handling of compressed files
Synthesis of the vulnerability
An attacker can generate an infinite loop in the handling of compressed files in CUPS, in order to trigger a denial of service.
Impacted products: CUPS.
Severity: 2/4.
Consequences: denial of service on service.
Provenance: user shell.
Creation date: 09/06/2015.
Identifiers: 4602, VIGILANCE-VUL-17082.
Description of the vulnerability
CUPS us a printing management system for Unix platforms.
It can receive file to be printed in Gzip compressed form. However, the Gzip format is not well checked and one kind of ill formed file leads to an endless loop.
An attacker can therefore generate an infinite loop in the handling of compressed files in CUPS, in order to trigger a denial of service.

CUPS: privilege escalation via the dynamic linker
Synthesis of the vulnerability
An attacker can bypass access restrictions to administrative functions of CUPS, in order to escalate his privileges.
Impacted products: CUPS, Debian, Fedora, Junos Space, openSUSE, RHEL, Slackware, SUSE Linux Enterprise Desktop, SLES, Ubuntu.
Severity: 2/4.
Consequences: administrator access/rights, privileged access/rights, user access/rights.
Provenance: user shell.
Creation date: 08/06/2015.
Revision date: 09/06/2015.
Identifiers: 4609, CERTFR-2015-AVI-431, CVE-2015-1158, DSA-3283-1, FEDORA-2015-9726, FEDORA-2015-9801, JSA10702, openSUSE-SU-2015:1056-1, RHSA-2015:1123-01, SSA:2015-188-01, SUSE-SU-2015:1011-1, SUSE-SU-2015:1041-1, SUSE-SU-2015:1044-1, SUSE-SU-2015:1044-2, USN-2629-1, VIGILANCE-VUL-17079, VU#810572.
Description of the vulnerability
CUPS us a printing management system for Unix platforms.
It includes a Web interface, used for instance to submit print jobs. However, ill formed requests with more than one "nameWithLanguage" attributes lead to the ability to override a configuration file. This allows the attacker to modify the environment of launched programs with SetEnv commands, and so, via LD_PRELOAD variables, to make launched programs load and run external code compiled as shared object.
An attacker can therefore bypass access restrictions to administrative functions of CUPS, in order to escalate his privileges.
