| Problem Description |
Buffer overflow in the LWZReadByte() function in gd_gif_in.c in GD
prior to 2.0.34 allows remote attackers to have an unknown impact
via a GIF file with input_code_size greater than MAX_LWZ_BITS, which
triggers an overflow when initializing the table array.
This was originally fixed in PHP's embedded GD with MDKSA-2006:162;
patches had not been applied to the system libgd at that time.
The updated packages have been patched to correct this issue.
