Notes

jdstrand

note this is gdImageCreate and gdImageCreateTrueColor dapper-gutsy libgd2 are affected to varying degrees php5-gd segfaults on feisty and gutsy before patching libgd2, and dapper-gutsy segfault after (this is because feisty-gutsy had a partial fix already in libgd2). php5-gd is not handling the error condition when libgd2 fails properly. Verified that 5.2.4 works with patched libgd2.
