TECHNICAL SUMMARY:

An Unspecified Memory Corruption Vulnerability has been discovered in Adobe Shockwave Player, which could allow for an attacker to execute arbitrary code or crash the application. The vulnerability can be exploited by the attacker crafting a malicious Shockwave file and attaching it to an email or creating a malicious webpage the user interacts with.

Successfully exploiting this vulnerability may allow an attacker to run arbitrary code in the context of the user running the affected application. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights. Failed attacks can result in a denial of service condition.

 

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Apply available patch from Adobe immediately after appropriate testing.

  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.

  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.

  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
