libtiff-3.8.2-19.AXS3

The libtiff package contains a library of functions for manipulating TIFF (Tagged Image File Format) image format files. TIFF is a widely used file format for bitmapped images. TIFF files usually end in the .tif extension and they are often quite large.

The libtiff package should be installed if you need to manipulate TIFF format image files.

Security issues fixed with this release:

• CVE-2013-1960
Heap-based buffer overflow in the t2p_process_jpeg_strip function in tiff2pdf in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image file.

• CVE-2013-1961
Stack-based buffer overflow in the t2p_write_pdf_page function in tiff2pdf in libtiff before 4.0.3 allows remote attackers to cause a denial of service (application crash) via a crafted image length and resolution in a TIFF image file.

• CVE-2013-4231
Multiple buffer overflows in libtiff before 4.0.3 allow remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) extension block in a GIF image or (2) GIF raster image to tools/gif2tiff.c or (3) a long filename for a TIFF image to tools/rgb2ycbcr.c. NOTE: vectors 1 and 3 are disputed by Red Hat, which states that the input cannot exceed the allocated buffer size.

• CVE-2013-4232
Use-after-free vulnerability in the t2p_readwrite_pdf_image function in tools/tiff2pdf.c in libtiff 4.0.3 allows remote attackers to cause a denial of service (crash) or possible execute arbitrary code via a crafted TIFF image.

• CVE-2013-4243
Heap-based buffer overflow in the readgifimage function in the gif2tiff tool in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted height and width values in a GIF image.

• CVE-2013-4244
The LZW decompressor in the gif2tiff tool in libtiff 4.0.3 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted GIF image.
