Off-by-one error in the bmp_rle4_fread function in pngxrbmp.c in OptiPNG before 0.7.6 allows remote attackers to cause a denial of service (out-of-bounds read or write access and crash) or possibly execute arbitrary code via a crafted image file, which triggers a heap-based buffer overflow.

The Sleipnir Mobile application 2.12.1 and earlier and Sleipnir Mobile Black Edition application 2.12.1 and earlier for Android provide Geolocation API data without verifying user consent, which allows remote attackers to obtain sensitive location information via a web site that makes API calls.
