Detailsinfo

A vulnerability was found in LibTIFF 4.0.9 (Image Processing Software). It has been classified as critical. Affected is the function TIFFFindField of the file tif_dirinfo.c. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in LibTIFF 4.0.9. In TIFFFindField in tif_dirinfo.c, the structure tif is being dereferenced without first checking that the structure is not empty and has the requested fields (tif_foundfield). In the call sequences following from the affected library functions (TIFFVGetField, TIFFVGetFieldDefaulted, TIFFVStripSize, TIFFScanlineSize, TIFFTileSize, TIFFGetFieldDefaulted, and TIFFGetField), this sanitization of the tif structure is never being done and, hence, using them with an invalid or empty tif structure will trigger a buffer overflow, leading to a crash.

The bug was discovered 07/18/2018. The weakness was published 07/17/2018 (Website). The advisory is shared for download at bugzilla.maptools.org. This vulnerability is traded as CVE-2018-14373 since 07/17/2018. There are known technical details, but no exploit is available.
