A crafted image file can trigger `stbi__load_gif_main_outofmem` attempt to double-free the out variable. This happens in `stbi__load_gif_main` because when the `layers * stride` value is zero the behavior is implementation defined, but common that realloc frees the old memory and returns null pointer. Since it attempts to double-free the memory a few lines below the first \"free\", the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2023-45664","url":"https://www.suse.com/security/cve/CVE-2023-45664"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1216478 for CVE-2023-45664","url":"https://bugzilla.suse.com/1216478"}],"title":"SUSE CVE CVE-2023-45664","tracking":{"current_release_date":"2025-12-19T01:19:28Z","generator":{"date":"2024-06-04T12:28:35Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2023-45664","initial_release_date":"2024-06-04T12:28:35Z","revision_history":[{"date":"2024-06-04T12:28:35Z","number":"2","summary":"Current version"},{"date":"2025-01-01T01:52:51Z","number":"3","summary":"Current version"},{"date":"2025-02-14T06:11:40Z","number":"4","summary":"Current version"},{"date":"2025-02-16T06:04:48Z","number":"5","summary":"Current version"},{"date":"2025-12-17T01:10:37Z","number":"6","summary":"description changed"},{"date":"2025-12-19T01:19:28Z","number":"7","summary":"description changed"}],"status":"interim","version":"7"}}}
