CVE-2018-5819
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 · uneditedAn error within the "parse_sinar_ia()" function (internal/dcraw_common.cpp) within LibRaw versions prior to 0.19.1 can be exploited to exhaust available CPU resources.
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 · high confidenceA denial of service vulnerability exists in LibRaw versions prior to 0.19.1. The parse_sinar_ia() function in internal/dcraw_common.cpp contains an error that can be exploited to exhaust available CPU resources, causing the application to become unresponsive.

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.
-
Check if LibRaw library is installedOn Debian-based systems: dpkg -l | grep libraw or rpm -qa | grep libraw. On Linux generally: locate libraw.so or find /usr -name 'libraw*' 2>/dev/nullAffected if LibRaw is installed and the version is unknown or below 0.19.1
-
Determine installed LibRaw versionRun: dpkg -l libraw0 or rpm -qi libraw, or check the library file version with: strings /path/to/libraw.so | grep -i version or readelf -d /path/to/libraw.so | grep versionAffected if Version is not found or is lower than 0.19.1
-
Check if dcraw_common.cpp component is presentLocate the internal/dcraw_common.cpp file or the compiled library that contains the parse_sinar_ia function: find / -path '*internal/dcraw_common.cpp' 2>/dev/null or nm -C /path/to/libraw.so | grep parse_sinar_iaAffected if The parse_sinar_ia function exists in the installed LibRaw library (indicating the vulnerable code path is present)
-
Verify Sinar camera raw file support is enabledCheck LibRaw configuration or test with a Sinar-format raw file (.si, .ia extension). Review application code or LibRaw initialization to see if Sinar_ia detection is active: grep -r 'sinar' /path/to/libraw/include 2>/dev/null or check application logs for Sinar/IA parsingAffected if Sinar IA raw file parsing is enabled or the application processes raw camera files from Sinar cameras
A system is affected if LibRaw version is installed and is lower than 0.19.1, with the vulnerable parse_sinar_ia function present and Sinar raw file parsing enabled.
