Operating system: Debian Linux 2.2.10 on P2
PHP version: 3.0.12
PHP Bug Type: Reproduceable crash
Bug description: php3_imagecreatefromgif doesn't check the return value of
gdImageCreateFromGif
Using 3.0.12 from Debian as a CGI
In functions/gd.c -- void php3_imagecreatefromgif
the function call gdImageCreateFromGif but doesn't check for its return value.
If the .gif is not valid then gdImageCreateFromGif return NULL that makes the php segfault.
Bye
