Opening a crafted file needs no privileges (PR:N over the vendor's PR:L) but requires local file-open interaction (AV:L/UI:R); a heap overflow to code execution yields full C:H/I:H/A:H.

2DescriptionCVE.org
A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.
AnalysisAI
Heap-based buffer overflow in GIMP's Paint Shop Pro (PSP) image format parser lets an attacker achieve arbitrary code execution or crash the application when a victim opens a maliciously crafted PSP file. The flaw stems from incorrect buffer-size arithmetic on low bit-depth images, and affects GIMP as shipped across Red Hat Enterprise Linux 6 through 9. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; exploitation requires local file-open interaction (CVSS 7.3).
Technical ContextAI
GIMP is a widely used open-source raster image editor that includes native import plug-ins for many legacy formats, including the Paint Shop Pro (PSP/PSPImage) format. The vulnerability lives in the PSP loader's handling of low bit-depth (e.g. 1/4/8-bit indexed) image blocks, where the code miscalculates the size of a heap allocation relative to the decoded pixel/channel data, then writes past the end of that buffer. This is classic CWE-122 (heap-based buffer overflow): attacker-controlled dimensions/bit-depth fields in the file header drive an undersized allocation, and subsequent copy operations overwrite adjacent heap metadata or objects, which can be leveraged for control-flow hijack or a straightforward crash. The Red Hat CPEs indicate the affected distribution channel is the GIMP package bundled with RHEL 6/7/8/9 rather than a RHEL OS component itself.
RemediationAI
Apply the vendor GIMP package update once released for your RHEL version; the upstream code fix is available as GNOME GIMP commit https://gitlab.gnome.org/GNOME/gimp/-/commit/b630f167, so this is best described as an upstream fix available (commit); a released patched RHEL package version is not independently confirmed in the provided data, so monitor https://access.redhat.com/security/cve/CVE-2026-58379 for the errata and exact fixed NEVRA. Until the patched package is installed, the most effective compensating control is to avoid opening untrusted or unsolicited PSP/PSPImage files in GIMP and to treat PSP attachments from email or the web as hostile; where feasible, remove or disable the PSP import plug-in from the GIMP plug-ins directory (trade-off: legitimate PSP files can no longer be opened) and open unknown images in a sandboxed or non-privileged session to limit the blast radius of a successful overwrite. Do not rely on file extension filtering alone, since the format is identified by content.
