Technical details
The file-psd plugin in GIMP fails to properly validate the channel-count parameter when parsing specially crafted PSD image files. This insufficient validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. An attacker can exploit this by distributing a malicious PSD file; when a user opens it in GIMP, the plugin will crash or leak memory contents. The vulnerability requires user interaction (opening a malicious file) and is network-reachable if files are downloaded or received via email. A patch should be available from GIMP maintainers.
