Information-disclosure vulnerability in Netsurf through 2.8 due to a world-readable cookie jar.

libnsbmp.c in Libnsbmp 0.1.2 allows context-dependent attackers to cause a denial of service (out-of-bounds read) via a crafted color table to the (1) bmp_decode_rgb or (2) bmp_decode_rle function.

Stack-based buffer overflow in the gif_next_LZW function in libnsgif.c in Libnsgif 0.1.2 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted LZW stream in a GIF file.

The gif_next_LZW function in libnsgif.c in Libnsgif 0.1.2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted LZW stream in a GIF file.

Heap-based buffer overflow in the bmp_decode_rle function in libnsbmp.c in Libnsbmp 0.1.2 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via the last row of RLE data in a crafted BMP file.

Surf-Net ASP Forum before 2.30 uses easily guessable cookies based on the UserID, which allows remote attackers to gain administrative privileges by calculating the value of the admin cookie (UserID 1), i.e. "0888888."
