TITLE

Realnetworks RealPlayer Vulnerable to arbitrary code execution

DESCRIPTION

Heap-based buffer overflow in RealNetworks RealPlayer 10; RealPlayer 10.5 6.0.12.1040 through 6.0.12.1741; RealPlayer 11 11.0.0 through 11.0.4; RealPlayer Enterprise; Mac RealPlayer 10, 10.1, and 11.0; Linux RealPlayer 10; and Helix Player 10.x allows remote attackers to execute arbitrary code via an SIPR codec field with a small length value that triggers incorrect memory allocation. This vulnerability allows remote attackers to execute code on vulnerable installations of RealNetworks RealPlayer. User interaction is required in that a user must open a malicious file or visit a malicious web site.The specific flaw exists during the parsing of SIPR codec fields. Specifying a small length value can trigger an undersized heap allocation. This buffer can then subsequently be overflowed. This vulnerability can result in arbitrary code execution under the context of the currently logged in user. RealPlayer SP, RealPlayer, and Helix Player are prone to multiple remote vulnerabilities, including heap- and stack-based buffer-overflow issues. A remote attacker could exploit these issues by crafting a file and enticing an unsuspecting user to open it using a vulnerable application. Failed exploit attempts will result in a denial-of-service condition. The following are vulnerable: RealPlayer SP 1.0.0 through 1.0.1 RealPlayer 11 11.0.0 through 11.0.5 RealPlayer 10.5 6.0.12.1040 through 6.0.12.163, 6.0.12.1675, 6.0.12.1698, and 6.0.12.1741 RealPlayer 10 and 10.1 Helix Player 11.0.0 through 11.0.2. A heap buffer overflow vulnerability exists in version x. ---------------------------------------------------------------------- Secunia integrated with Microsoft WSUS http://secunia.com/blog/71/ ---------------------------------------------------------------------- TITLE: RealPlayer Multiple Vulnerabilities SECUNIA ADVISORY ID: SA38218 VERIFY ADVISORY: http://secunia.com/advisories/38218/ DESCRIPTION: Some vulnerabilities have been reported in RealPlayer, which can be exploited by malicious people to compromise a vulnerable system. 1) An unspecified error related to the RealPlayer ASM Rulebook can be exploited to cause a heap-based buffer overflow. 2) An unspecified error when processing GIF images can be exploited to cause a heap-based buffer overflow. 3) A vulnerability is caused due to an unspecified error related to HTTP chunk encoding. 4) An unspecified error within the RealPlayer SIPR codec can be exploited to cause a heap-based buffer overflow. 5) An unspecified error when processing compressed GIF images can be exploited to cause a heap-based buffer overflow. 6) An unspecified error within the RealPlayer SMIL parsing can be exploited to cause a heap-based buffer overflow. 7) An unspecified error within the RealPlayer skin parsing can be exploited to cause a stack-based buffer overflow. 8) An unspecified error related to the RealPlayer ASM RuleBook can be exploited to cause an "array overflow". 9) An unspecified boundary error related to RealPlayer RTSP "set_parameter" can be exploited to cause a buffer overflow. 10) Two vulnerabilities are caused due to errors within the processing of Internet Video Recording (IVR) files.
