PackageArchVulnerableUnaffected
net-print/cups*< 1.3.10>= 1.3.10

Background

CUPS, the Common Unix Printing System, is a full-featured print server.

Description

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.

Impact

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.

Impact

A malicious user might be able to execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service by sending a specially crafted PNG image to the print server. The vulnerability is exploitable via the network if CUPS is sharing printers remotely.

Background

CUPS provides a portable printing layer for UNIX-based operating systems.

Description

Multiple vulnerabilities have been reported in CUPS:

  • regenrecht (VeriSign iDefense) discovered that the cgiCompileSearch() function used in several CGI scripts in CUPS' administration interface does not correctly calculate boundaries when processing a user-provided regular expression, leading to a heap-based buffer overflow (CVE-2008-0047).
  • Helge Blischke reported a double free() vulnerability in the process_browse_data() function when adding or removing remote shared printers (CVE-2008-0882).
  • Tomas Hoger (Red Hat) reported that the gif_read_lzw() function uses the code_size value from GIF images without properly checking it, leading to a buffer overflow (CVE-2008-1373).
  • An unspecified input validation error was discovered in the HP-GL/2 filter (CVE-2008-0053).

Impact

A local attacker could send specially crafted network packets or print jobs and possibly execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service. The vulnerabilities are exploitable via the network when CUPS is sharing printers remotely.

PackageArchVulnerableUnaffected
net-print/cups*< 1.3.5>= 1.2.12-r4 (revision), >= 1.3.5

Background

CUPS provides a portable printing layer for UNIX-based operating systems. The alternate pdftops filter is a CUPS filter used to convert PDF files to the Postscript format via Poppler; the filter is installed by default in Gentoo Linux.

Description

Wei Wang (McAfee AVERT Research) discovered an integer underflow in the asn1_get_string() function of the SNMP backend, leading to a stack-based buffer overflow when handling SNMP responses (CVE-2007-5849). Elias Pipping (Gentoo) discovered that the alternate pdftops filter creates temporary files with predictable file names when reading from standard input (CVE-2007-6358). Furthermore, the resolution of a Denial of Service vulnerability covered in GLSA 200703-28 introduced another Denial of Service vulnerability within SSL handling (CVE-2007-4045).

Impact

A remote attacker on the local network could exploit the first vulnerability to execute arbitrary code with elevated privileges by sending specially crafted SNMP messages as a response to an SNMP broadcast request. A local attacker could exploit the second vulnerability to overwrite arbitrary files with the privileges of the user running the CUPS spooler (usually lp) by using symlink attacks. A remote attacker could cause a Denial of Service condition via the third vulnerability when SSL is enabled in CUPS.

Workaround

To disable SNMP support in CUPS, you have have to manually delete the file "/usr/libexec/cups/backend/snmp". Please note that the file is reinstalled if you merge CUPS again later. To disable the pdftops filter, delete all lines referencing "pdftops" in CUPS' "mime.convs" configuration file. To work around the third vulnerability, disable SSL support via the corresponding USE flag.

net-print/cups*< 1.2.12-r2>= 1.2.12-r2

Background

CUPS provides a portable printing layer for UNIX-based operating systems.

Description

Alin Rad Pop (Secunia Research) discovered an off-by-one error in the ippReadIO() function when handling Internet Printing Protocol (IPP) tags that might allow to overwrite one byte on the stack.

Impact

A local attacker could send a specially crafted IPP request containing "textWithLanguage" or "nameWithLanguage" tags, leading to a Denial of Service or the execution of arbitrary code with the privileges of the "lp" user. If CUPS is configured to allow network printing, this vulnerability might be remotely exploitable.

Workaround

To avoid remote exploitation, network access to CUPS servers on port 631/udp should be restricted. In order to do this, update the "Listen" setting in cupsd.conf to "Listen localhost:631" or add a rule to the system's firewall. However, this will not avoid local users from exploiting this vulnerability.

Description

CUPS does not properly handle partially-negotiated SSL connections. Upon receiving a partially-negotiated SSL connection, CUPS no longer accepts further incoming connections, as the initial connection never times out.

Impact

An attacker could partially negotiate an SSL connection with a CUPS server, and cause future connections to that server to fail, resulting in a Denial of Service.

Description

Background

The Common UNIX Printing System (CUPS) is a cross-platform print spooler, hpgltops is a CUPS filter handling printing of HPGL files and lppasswd is a program used locally to manage spooler passwords.

Description

CUPS makes use of vulnerable Xpdf code to handle PDF files (CAN-2004-1125). Furthermore, Ariel Berkman discovered a buffer overflow in the ParseCommand function in hpgl-input.c in the hpgltops program (CAN-2004-1267). Finally, Bartlomiej Sieka discovered several problems in the lppasswd program: it ignores some write errors (CAN-2004-1268), it can leave the passwd.new file in place (CAN-2004-1269) and it does not verify that passwd.new file is different from STDERR (CAN-2004-1270).

Impact

The Xpdf and hpgltops vulnerabilities may be exploited by a remote attacker to execute arbitrary code by sending specific print jobs to a CUPS spooler. The lppasswd vulnerabilities may be exploited by a local attacker to write data to the CUPS password file or deny further password modifications.
