GIMP image editor 2.8.18, a new point release in the stable branch, has been released to fix a vulnerability in the XCF loading code. With special XCF files, GIMP can be caused to crash, and possibly be made to execute arbitrary code provided by the attacker.
Besides this security fix, GIMP 2.8.18 also brings following changes:
- Fix “GIMP is not responding” on initial startup on Windows and OS X.
- Fix GUI crashed on OS X
- Fix gamut warning color for lcms display filter
- Fix unbolding of bold font on edit
- Decrease installer size by changing compression settings
- Many other fixes, translation and documentation updates.
