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.
