DESCRIPTION:
Francis Provencher has discovered multiple vulnerabilities in ACDSee
Pro, which can be exploited by malicious people to potentially
compromise a user's system.

1) Insufficient validation in ID_ICO.apl when copying colours from
cursors in .CUR files can be exploited to cause a heap-based buffer
overflow via a .CUR file containing a specially crafted
"ColorsImportant" field value.

2) An error in IDE_ACDStd.apl when allocating memory based on values
in the Logical Screen Descriptor structure of a GIF image and later
copying data into the buffer without ensuring that it's adequately
sized can be exploited to corrupt heap memory.

3) Insufficient validation in ID_PICT.apl of specific byte values
used as sizes in the image content can be exploited to cause a
heap-based buffer overflow via a specially crafted .PCT file.

4) Insufficient validation in IDE_ACDStd.apl of specific byte values
used as sizes in the image content when decompressing run-length
encoded bitmaps can be exploited to cause a heap-based buffer
overflow via a specially crafted .RLE file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

The vulnerabilities are confirmed in version 5.1 (Build 137). Other
versions may also be affected.

SOLUTION:
Update to version 5.2 (Build 157).
