The GIF loader in imlib2 before 1.4.9 allows remote attackers to cause a denial of service (application crash) or obtain sensitive information via a crafted image, which triggers an out-of-bounds read.

Integer overflow in imlib2 before 1.4.9 on 32-bit platforms allows remote attackers to execute arbitrary code via large dimensions in an image, which triggers an out-of-bounds heap memory write operation.

Off-by-one error in the __imlib_MergeUpdate function in lib/updates.c in imlib2 before 1.4.9 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted coordinates.

imlib2 before 1.4.9 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) by drawing a 2x1 ellipse.

Multiple heap-based buffer overflows in imlib2 1.4.3 allow context-dependent attackers to execute arbitrary code via a crafted (1) ARGB, (2) XPM, or (3) BMP file, related to the IMAGE_DIMENSIONS_OK macro in lib/image.h.

An issue in the imlib_free_image_and_decache function of imlib2 v1.9.1 allows attackers to cause a heap buffer overflow via parsing a crafted image.

modules/loaders/loader_ico.c in imlib2 1.6.0 has an integer overflow (with resultant invalid memory allocations and out-of-bounds reads) via an icon with many colors in its color map.
