If the CUPS server (cupsd) receives a zero-length UDP message, it will disable its print queue browser service.

Ariel Berkman has discovered a buffer overflow vulnerability in CUPS's HPGL input driver. This vulnerability could be exploited to execute arbitrary code with the permission of the CUPS server by printing a specially crated HPGL file.

CUPS reports:

The PNG image reading code did not validate the image size properly, leading to a potential buffer overflow (STR #2974)

Secunia Research reports:

Secunia Research has discovered some vulnerabilities in Xpdf, which can be exploited by malicious people to compromise a user's system.

• An array indexing error within the "DCTStream::readProgressiveDataUnit()" method in xpdf/Stream.cc can be exploited to corrupt memory via a specially crafted PDF file.
• An integer overflow error within the "DCTStream::reset()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow via a specially crafted PDF file.
• A boundary error within the "CCITTFaxStream::lookChar()" method in xpdf/Stream.cc can be exploited to cause a heap-based buffer overflow by tricking a user into opening a PDF file containing a specially crafted "CCITTFaxDecode" filter.

Successful exploitation may allow execution of arbitrary code.

An iDEFENSE Security Advisory reports:

Remote exploitation of a buffer overflow vulnerability in the xpdf PDF viewer included in multiple Unix and Linux distributions could allow for arbitrary code execution as the user viewing a PDF file.

The vulnerability specifically exists due to insufficient bounds checking while processing a PDF file that provides malicious values in the /Encrypt /Length tag. The offending code can be found in the Decrypt::makeFileKey2 function in the source file xpdf/Decrypt.cc.

The release note of cups 1.3.9 reports:

It contains the following fixes:

• SECURITY: The HP-GL/2 filter did not range check pen numbers (STR #2911)
• SECURITY: The SGI image file reader did not range check 16-bit run lengths (STR #2918)
• SECURITY: The text filter did not range check cpi, lpi, or column values (STR #2919)

Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the affected service.

Chris Evans discovered several integer arithmetic overflows in the xpdf 2 and xpdf 3 code bases. The flaws have impacts ranging from denial-of-service to arbitrary code execution.

Secunia reports:

Secunia Research has discovered a vulnerability in CUPS, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the "ippReadIO()" function in cups/ipp.c when processing IPP (Internet Printing Protocol) tags. This can be exploited to overwrite one byte on the stack with a zero by sending an IPP request containing specially crafted "textWithLanguage" or "nameWithLanguage" tags.

Successful exploitation allows execution of arbitrary code.

< 1.3.3_1

xpdf is vulnerable to a denial of service vulnerability which can cause xpdf to create an infinitely large file, thereby filling up the /tmp partition, when opening a specially crafted PDF file.

Note that several applications contains an embedded version of xpdf, therefor making them the vulnerable to the same DoS. In CUPS this vulnerability would cause the pdftops filter to crash.

Gentoo security team summarizes:

The following issues were reported in CUPS:

• iDefense reported an integer overflow in the _cupsImageReadTIFF() function in the "imagetops" filter, leading to a heap-based buffer overflow (CVE-2009-0163).
• Aaron Siegel of Apple Product Security reported that the CUPS web interface does not verify the content of the "Host" HTTP header properly (CVE-2009-0164).
• Braden Thomas and Drew Yao of Apple Product Security reported that CUPS is vulnerable to CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166, found earlier in xpdf and poppler.

A remote attacker might send or entice a user to send a specially crafted print job to CUPS, possibly resulting in the execution of arbitrary code with the privileges of the configured CUPS user -- by default this is "lp", or a Denial of Service. Furthermore, the web interface could be used to conduct DNS rebinding attacks.

The KDE Team reports:

kpdf, the KDE pdf viewer, shares code with xpdf. xpdf contains a vulnerability that can cause a stack based buffer overflow via a PDF file that exploits an integer overflow in StreamPredictor::StreamPredictor(). Remotely supplied pdf files can be used to disrupt the kpdf viewer on the client machine and possibly execute arbitrary code.

An iDEFENSE Security Advisory reports:

CUPS development team reports:

The new release addresses two security vulnerabilities, add localizations for German and Russian, and includes several general bug fixes. Changes include:

Security: Fixed CERT VU #810572/CVE-2015-1158/CVE-2015-1159 exploiting the dynamic linker (STR #4609)

Security: The scheduler could hang with malformed gzip data (STR #4602)

Secunia reports:

CUPS is not using multiple workers to handle connections. This can be exploited to stop CUPS from accepting new connections by starting but never completing an SSL negotiation.

< 1.2.11

Certain methods of authenticated remote printing in CUPS can disclose user names and passwords in the log files.

A workaround for this problem is to set more strict access permissions on the CUPS logfiles.
