The overflow could cause Adobe Acrobat to crash could also result in remote code execution if malicious content is inserted into a PDF file, according to an advisory released this week by Adobe.
Adobe, based in San Jose, Calif., recommended that both Microsoft Windows and Macintosh users of Acrobat take advantage of the product's automatic update to install version 6.0.5 or download an update from the company's support site.
The flaw is considered critical by the company, according to the advisory.
Adobe, which discovered the flaws through internal software testing, released the bulletins to meet customer requirements for secure software. The company had not received any reports of exploits for these flaws, said Matt Rozen, Adobe spokesman.
