CVE-2026-2272: Integer Overflow or Wraparound in Red Hat Red Hat Enterprise Linux 6
A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.
AI Analysis
Technical Summary
An integer overflow vulnerability exists in GIMP's ICO image processing on Red Hat Enterprise Linux 6, specifically in the ico_read_info and ico_read_icon functions. The vulnerability arises from a 32-bit integer evaluation that causes size calculations for image buffers to wrap around, enabling oversized image headers to bypass security checks. This can lead to buffer overflow and memory corruption, resulting in an application-level denial of service. The CVSS 3.1 base score is 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L). No patch or remediation information is provided in the vendor advisory content.
Potential Impact
Exploitation of this vulnerability can cause an application-level denial of service due to memory corruption from a buffer overflow triggered by a specially crafted ICO file. There is no indication of confidentiality or integrity impact. No known exploits in the wild have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-2272 for current remediation guidance. Until an official fix is available, avoid processing untrusted ICO image files with vulnerable versions of GIMP on Red Hat Enterprise Linux 6.
