Summary
Vulnerability in libtiff library. A remote attacker can supply a specially crafted PixarLog-compressed TIFF image. The issue occurs when decoding Pixarlog codec images with PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could result in arbitrary code execution or denial of service (DoS).
Risk Assessment
Risk includes remote code execution or system crash, potentially leading to application takeover or unavailability.
Recommendation
Update libtiff to the latest patched version and avoid processing untrusted TIFF images.

- CVE-2017-17942High
In LibTIFF version 4.0.9, there is a heap-based buffer over-read in the function PackBitsEncode in tif_packbits.c.
- CVE-2017-17095High
The pal2rgb tool in LibTIFF 4.0.9 has a vulnerability that allows remote attackers to cause application crashes via a crafted TIFF file due to a heap-based buffer overflow.
- CVE-2017-12944High
The TIFFReadDirEntryArray function in LibTIFF 4.0.8 mishandles memory allocation for short files, potentially leading to application crashes during tiff2pdf invocation.
- CVE-2017-11335High
There is a heap based buffer overflow in LibTIFF 4.0.8 in tools/tiff2pdf.c triggered by a PlanarConfig=Contig image. This can lead to an out-of-bounds write and potentially to remote denial of service or arbitrary code execution attacks.
- CVE-2017-10688High
In LibTIFF version 4.0.8, there is an assertion abort in the TIFFWriteDirectoryTagCheckedLong8Array function in tif_dirwrite.c. Crafted input can lead to a remote denial of service attack.
- CVE-2017-9935High
In LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf function, which could lead to various damages. A crafted TIFF document can lead to out-of-bounds read, invalid free, or memory corruption, potentially allowing arbitrary code execution.
- CVE-2017-7602High
LibTIFF version 4.0.7 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
- CVE-2017-7601High
LibTIFF version 4.0.7 has an undefined behavior issue related to 'shift exponent too large for 64-bit type long', which may lead to application crashes.
- CVE-2017-7600High
LibTIFF version 4.0.7 has an undefined behavior issue related to values outside the range of representable values of type unsigned char, which may allow remote attackers to cause application crashes or possibly have unspecified other impacts via a crafted image.
Original NVD description (English source)
A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).
