Summary
A flaw was found in the file-xwd plugin in GIMP. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read.
This issue can result in an application crash, leading to a denial of service, or a limited information disclosure of heap memory contents into the produced image. To exploit this vulnerability, an attacker needs to convince a user to process a specially crafted XWD image with GIMP, reducing the likelihood of exploitation.
Due to this reason, this flaw has been rated with a moderate severity. Red Hat severity: Moderate — CVSS 4.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L).
Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat does not currently list a fixing RHSA for this CVE.
Affected products named by the advisory: Red Hat package: gimp-devel-tools; Red Hat package: gimp-help-browser; Red Hat package: gimp-libs; Red Hat package: gimp.src.
