A vulnerability was found in saitoha libsixel up to 1.10.3. Affected by this issue is the function sixel_debug_print_palette of the file src/encoder.c of the component img2sixel. The manipulation results in stack-based buffer overflow. The attack mus...

There is a floating point exception error in sixel_encoder_do_resize, encoder.c:633 in libsixel img2sixel 1.8.6. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted JPEG file.

There is an assertion failure error in stbi__jpeg_huff_decode, stb_image.h:1894 in libsixel img2sixel 1.8.6. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted JPEG file.

libsixel before 1.10 is vulnerable to Buffer Overflow in libsixel/src/quant.c:867.

libsixel 1.8.6 suffers from a Heap Use After Free vulnerability in in libsixel/src/dither.c:388.

libsixel 1.8.6 is affected by Buffer Overflow in libsixel/src/quant.c:876.

libsixel 1.10.0 is vulnerable to Use after free in libsixel/src/dither.c:379.
