DescriptionImager versions before 1.037 for Perl overflow a heap buffer fetching float samples from a paletted image in i_gsampf_fp. For a paletted image, getsamples() with type "float" allocates a buffer of one sample per pixel and fetches every requested channel of each pixel into it. Requesting more than one channel writes past its end. An attacker-supplied image controls the overflowing bytes through its palette.

Risk And Classification

Problem Types: CWE-131 | CWE-131 CWE-131 Incorrect Calculation of Buffer Size
