System access

This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.

Multiple vulnerabilities have been reported in RealPlayer/RealOne/HelixPlayer, which can be exploited by malicious people to compromise a user's system.

1) An integer overflow error when processing Lyrics3 v2.00 tags in MP3 files can be exploited to cause a heap-based buffer overflow via a specially crafted MP3 file.

2) An input validation error when processing .RA/.RAM files can be exploited to cause a heap corruption via a specially crafted .RA/.RAM file with an overly large size field in the header.

3) An error in the processing of .PLS files can be exploited to cause a memory corruption and execute arbitrary code via a specially crafted .PLS file.

4) An input validation error when parsing .SWF files can be exploited to cause a buffer overflow via a specially crafted .SWF file with malformed record headers.

5) A boundary error when processing rm files can be exploited to cause a buffer overflow.

6) A boundary error when processing SMIL files can be exploited to cause a stack-based buffer overflow. For more information:
SA25819

Successful exploitation of the vulnerabilities allows execution of arbitrary code.
