Summary
A flaw was found in LibRaw, an open-source library for processing raw image files. This vulnerability is a buffer overflow, which occurs in the `stretch()` and `fuji_rotate()` functions.
A buffer overflow can allow an attacker to overwrite memory, potentially leading to a denial of service or the execution of unauthorized code. Successful exploitation requires a local attacker to trick a user into processing a specially crafted raw image file, which could lead to arbitrary code execution or a denial of service.
Red Hat Enterprise Linux 9 is affected, while Red Hat Enterprise Linux 8 and older versions are not vulnerable as they ship with older, unaffected versions of LibRaw or do not contain the vulnerable code. Red Hat severity: Important — CVSS 7.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).
Weakness: CWE-120. Affected Red Hat products: Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions; Red Hat Enterprise Linux 9.6 Extended Update Support.
