cups: password disclosure via debug log

The scheduler in CUPS in Apple Mac OS X 10.5 before 10.5.3, when debug logging is enabled and a printer requires a password, allows attackers to obtain sensitive information (credentials) by reading the log data, related to "authentication environment variables."

cups: incomplete fix for CVE-2004-0888 / CVE-2005-0206

Integer overflow in pdftops filter in CUPS in Red Hat Enterprise Linux 3 and 4, when running on 64-bit platforms, allows remote attackers to execute arbitrary code via a crafted PDF file. NOTE: this issue is due to an incomplete fix for CVE-2004-0888.

CUPS: SGI image parser heap-based buffer overflow

Heap-based buffer overflow in the read_rle16 function in imagetops in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via an SGI image with malformed Run Length Encoded (RLE) data containing a small image and a large row count.

CUPS: texttops integer overflow

Integer overflow in the WriteProlog function in texttops in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via a crafted PostScript file that triggers a heap-based buffer overflow.

CUPS: HP/GL reader insufficient bounds checking

The Hewlett-Packard Graphics Language (HPGL) filter in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via crafted pen width and pen color opcodes that overwrite arbitrary memory.

cups: DoS (daemon crash) caused by the large number of subscriptions

cupsd in CUPS 1.3.9 and earlier allows local users, and possibly remote attackers, to cause a denial of service (daemon crash) by adding a large number of RSS Subscriptions, which triggers a NULL pointer dereference. NOTE: this issue can be triggered remotely by leveraging CVE-2008-5184.

cups: improper use of the 'guest' username in the web UI, when user not logged on to the server

The web interface (cgi-bin/admin.c) in CUPS before 1.3.8 uses the guest username when a user is not logged on to the web server, which makes it easier for remote attackers to bypass intended policy and conduct CSRF attacks via the (1) add and (2) cancel RSS subscription functions.

cups: Incomplete fix for CVE-2008-1722

Integer overflow in the _cupsImageReadPNG function in CUPS 1.1.17 through 1.3.9 allows remote attackers to execute arbitrary code via a PNG image with a large height value, which bypasses a validation check and triggers a buffer overflow.

pstopdf in CUPS 1.3.8 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/pstopdf.log temporary file, a different vulnerability than CVE-2001-1333.

CUPS on Mandriva Linux 2008.0, 2008.1, 2009.0, Corporate Server (CS) 3.0 and 4.0, and Multi Network Firewall (MNF) 2.0 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/pdf.log temporary file.

xpdf: Multiple buffer overflows in JBIG2 decoder (setBitmap, readSymbolDictSeg) (CVE-2009-0195)

Multiple buffer overflows in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, and other products allow remote attackers to cause a denial of service (crash) via a crafted PDF file, related to (1) JBIG2SymbolDict::setBitmap and (2) JBIG2Stream::readSymbolDictSeg.

xpdf: Multiple integer overflows in JBIG2 decoder

Multiple integer overflows in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, and other products allow remote attackers to cause a denial of service (crash) via a crafted PDF file, related to (1) JBIG2Stream::readSymbolDictSeg, (2) JBIG2Stream::readSymbolDictSeg, and (3) JBIG2Stream::readGenericBitmap.

cups: Integer overflow in the TIFF image filter

Integer overflow in the TIFF image decoding routines in CUPS 1.3.9 and earlier allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via a crafted TIFF image, which is not properly handled by the (1) _cupsImageReadTIFF function in the imagetops filter and (2) imagetoraster filter, leading to a heap-based buffer overflow.

cups: insufficient checking of the HTTP Host: header

The web interface for CUPS before 1.3.10 does not validate the HTTP Host header in a client request, which makes it easier for remote attackers to conduct DNS rebinding attacks.

Heap-based buffer overflow in Apple QuickTime on Mac OS 10.2.8 through 10.3.5 may allow remote attackers to execute arbitrary code via a certain BMP image.

security flaw

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to add printers without authentication via a certain UDP packet, which can then be used to perform unauthorized activities such as stealing the local root certificate for the administration server via a "need authorization" page, as demonstrated by new-coke.

security flaw

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing negative arguments to be fed into memcpy() calls via HTTP requests with (1) a negative Content-Length value or (2) a negative length in a chunked transfer encoding.

security flaw

jobs.c in Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly use the strncat function call when processing the options string, which allows remote attackers to execute arbitrary code via a buffer overflow attack.

security flaw

filters/image-gif.c in Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check for zero-length GIF images, which allows remote attackers to execute arbitrary code via modified chunk headers, as demonstrated by nogif.

security flaw

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service (resource exhaustion) by causing file descriptors to be assigned and not released, as demonstrated by fanta.
