Mandriva Linux Security Advisory 2009-264 – Multiple integer overflows in libgd in PHP before 5.2.4 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large (1) srcW or (2) srcH value to the (a) gdImageCopyResized function, or a large (3) sy (height) or (4) sx (width) value to the (b) gdImageCreate or the (c) gdImageCreateTrueColor function. The updated packages have been patched to prevent this.
