Apple Cups 1.1.18

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.

Multiple buffer overflows in the HP-GL/2-to-PostScript filter in CUPS before 1.3.6 might allow remote attackers to execute arbitrary code via a crafted HP-GL/2 file.

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.

Multiple buffer overflows in the JBIG2 MMR decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allow remote attackers to execute arbitrary code via a crafted PDF file.

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.

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.

Integer overflow in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to execute arbitrary code via a crafted PDF file.

Multiple "input validation flaws" in the JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allow remote attackers to execute arbitrary code via a crafted PDF file.

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to execute arbitrary code via a crafted PDF file that triggers a free of invalid data.

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.

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.

The _WriteProlog function in texttops.c in texttops in the Text Filter subsystem in CUPS before 1.4.4 does not check the return values of certain calloc calls, which allows remote attackers to cause a denial of service (NULL pointer dereference or heap memory corruption) or possibly execute arbitrary code via a crafted file.

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.

The gif_read_lzw function in filter/image-gif.c in CUPS 1.4.8 and earlier does not properly handle the first code word in an LZW stream, which allows remote attackers to trigger a heap-based buffer overflow, and possibly execute arbitrary code, via a crafted stream, a different vulnerability than CVE-2011-2896.

The cupsDoAuthentication function in auth.c in the client in CUPS before 1.4.4, when HAVE_GSSAPI is omitted, does not properly handle a demand for authorization, which allows remote CUPS servers to cause a denial of service (infinite loop) via HTTP_UNAUTHORIZED responses.

The cgi_initialize_string function in cgi-bin/var.c in the web interface in CUPS before 1.4.4, as used on Apple Mac OS X 10.5.8, Mac OS X 10.6 before 10.6.4, and other platforms, does not properly handle parameter values containing a % (percent) character without two subsequent hex characters, which allows context-dependent attackers to obtain sensitive information from cupsd process memory via a crafted request, as demonstrated by the (1) /admin?OP=redirect&URL=% and (2) /admin?URL=/admin/&OP=% URIs.

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (crash) via a crafted PDF file that triggers a NULL pointer dereference.

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (crash) via a crafted PDF file that triggers an out-of-bounds read.

The JBIG2 MMR decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to cause a denial of service (infinite loop and hang) via a crafted PDF file.

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.

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.

The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, and other products allows remote attackers to cause a denial of service (crash) via a crafted PDF file that triggers a free of uninitialized memory.

Cross-site scripting (XSS) vulnerability in scheduler/client.c in Common Unix Printing System (CUPS) before 1.7.2 allows remote attackers to inject arbitrary web script or HTML via the URL path, related to the is_path_absolute function.

The cupsFileOpen function in CUPS before 1.4.4 allows local users, with lp group membership, to overwrite arbitrary files via a symlink attack on the (1) /var/cache/cups/remote.cache or (2) /var/cache/cups/job.cache file.
