CVE-2008-5498: Infoleak
Array index error in the imageRotate function in PHP 5.2.8 and earlier allows context-dependent attackers to read the contents of arbitrary memory locations via a crafted value of the third argument (aka the bgdcolor or clrBack argument) for an indexed image.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
For PHP imageRotate calls on indexed images, validate/sanitize the third argument (bgd_color / clrBack) before use: ensure the value is an integer within the image palette bounds (0 through palette_size-1) and reject or clamp any out-of-range values. As an alternative mitigation, convert indexed images to truecolor before calling imageRotate so palette indices cannot be used to trigger the bug.
