Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.

The VMnc media codec in vmnc.dll in VMware Movie Decoder before 6.5.3 build 185404, VMware Workstation 6.5.x before 6.5.3 build 185404, VMware Player 2.5.x before 2.5.3 build 185404, and VMware ACE 2.5.x before 2.5.3 build 185404 on Windows does not properly handle certain small heights in video content, which might allow remote attackers to execute arbitrary code via a crafted AVI file that triggers heap memory corruption.

The frame decompression functionality in the VMnc media codec in VMware Movie Decoder before 6.5.5 build 328052 and 7.x before 7.1.2 build 301548, VMware Workstation 6.5.x before 6.5.5 build 328052 and 7.x before 7.1.2 build 301548 on Windows, VMware Player 2.5.x before 2.5.5 build 246459 and 3.x before 3.1.2 build 301548 on Windows, and VMware Server 2.x on Windows does not properly validate an unspecified size field, which allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted video file.
