Adobe investigating zero-day bug in Flash
Researchers on Wednesday said they have uncovered attacks in the wild in which malicious Acrobat PDF files are exploiting a vulnerability in Flash and dropping a Trojan onto computers.
The situation could affect tons of users since Flash exists in all popular browsers, is available in PDF files, and is largely operating system-independent.
Any software that uses Flash could be vulnerable to the attack, according to Symantec. Adobe Reader is vulnerable because its Flash interpreter is vulnerable, said Paul Royal, principal researcher at Purewire, a Web security services provider.
