CVE-2015-7313
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedLibTIFF before 4.0.7 allows remote attackers to cause a denial of service (memory consumption and crash) via a crafted tiff file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceLibTIFF before 4.0.7 contains a vulnerability where a specially crafted TIFF file can cause excessive memory allocation, leading to memory exhaustion and application crash. The vulnerability is exploitable remotely through file processing.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed LibTIFF versionRun 'tiffinfo -version' or check the shared library version with 'ldconfig -p | grep tiff' and examine the file version, or use 'dpkg -l libtiff*' (Debian) or 'rpm -qa | grep tiff' (RHEL)Affected if The installed version is below 4.0.7
-
Locate libtiff library filesFind libtiff.so or libtiff.dll files on the system using 'find /usr -name "libtiff*" 2>/dev/null' (Linux) or search the application directory (Windows)Affected if A LibTIFF library version below 4.0.7 exists on the system
-
Determine TIFF processing usageSearch application logs, dependencies, or configuration for TIFF handling code. Check if the application links against libtiff using 'ldd <executable>' or inspect imported modulesAffected if The system runs software that processes TIFF files using LibTIFF
-
Identify running services that accept file uploadsReview web applications, document processors, or image conversion services that may accept user-supplied TIFF filesAffected if Any service processes uploaded or network-received TIFF files without strict validation
-
Check for memory limits on file processingInspect application memory constraints or container/resource limits that would bound the exhaustion conditionAffected if No memory limits exist or limits are set excessively high, allowing exhaustion to occur
The environment is affected if LibTIFF version 4.0.7 or earlier is installed AND any application or service processes untrusted TIFF files using the vulnerable library.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data4.0.7
Upgrade LibTIFF to version 4.0.7 or later to patch the memory consumption vulnerability. Validate and sanitize untrusted TIFF files before processing.
