CVE-2014-5120

Published: 23 August 2014

gd_ctx.c in the GD component in PHP 5.4.x before 5.4.32 and 5.5.x before 5.5.16 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to overwrite arbitrary files via crafted input to an application that calls the (1) imagegd, (2) imagegd2, (3) imagegif, (4) imagejpeg, (5) imagepng, (6) imagewbmp, or (7) imagewebp function.

Notes

per Debian, php-specific

Not affected, already fixed via gdIOCtx.patch
