In sam2p 0.49.3, the inxpmreader function in inxpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element.

In sam2p 0.49.3, the pcxLoadRaster function in inpcx.cpp has an integer signedness error leading to a heap-based buffer overflow.

In sam2p 0.49.4, there are integer overflows (with resultant heap-based buffer overflows) in input-bmp.ci in the function ReadImage, because "width height" multiplications occur unsafely.

In sam2p 0.49.3, there is an invalid read of size 2 in the parsergb function in inxpm.cpp. However, this can also cause a write to an illegal address.

Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element.

There is a heap-based buffer overflow in bmpcompress1row in appliers.cpp in sam2p 0.49.4 that leads to a denial of service or possibly unspecified other impact.

There is a heap-based buffer overflow in ReadImage in input-tga.ci in sam2p 0.49.4 that leads to a denial of service or possibly unspecified other impact.

The DGifDecompressLine function in dgiflib.c in GIFLIB (possibly version 3.0.x), as later shipped in cgif.c in sam2p 0.49.4, has a heap-based buffer overflow because a certain CrntCode array index is not checked. This will lead to a denial of service or possibly unspecified other impact.

There is an invalid memory access bug in cgif.c that leads to a Segmentation fault in sam2p 0.49.4. A crafted input will lead to a denial of service or possibly unspecified other impact.

There is a floating point exception in ReadImage that leads to a Segmentation fault in sam2p 0.49.4. A crafted input will lead to a denial of service or possibly unspecified other impact.
