Apple

(AAPL) - Get Report

says that it is looking into a reported

iPhone

security breach after a slew of media reports suggested that the smartphone could be vulnerable to malicious code

unwittingly downloaded via a PDF.

Gizmodo

reports that users visiting a tampered-with Web site and loading a PDF could unknowingly open their devices up to hackers. In a blog post, Graham Cluley, senior technology consultant at antivirus specialist

Sophos

, said that the vulnerability is in

the mobile version of the Safari Web browser

used by Apple's operating system, specifically its handling of PDFs.

In addition to iPhones, Gizmodo reports that iPads and the iPod Touch could also be susceptible to the vulnerability. All iPhones, iPod Touches and iPads running version 3.1.2 of Apple's iOS operating system and higher could be at risk, it added.

"We're aware of the reports, and we're investigating," an Apple spokeswoman told

TheStreet

Thursday, but declined to provide any additional details.

The furor over the reported security glitch has been gaining momentum. Germany's Federal Office for Information Security, for example, warned consumers that Apple's

iOS has "two critical" vulnerabilities

for which "no patch is yet available."

The agency warned that the weaknesses could cause an Apple mobile device to be infected by malicious software that would allow hackers to access a user's personal information.

Security specialist

Symantec

(SYMC) - Get Report

has also urged consumers

to be on their guard

. In a statement, Symantec explained that a new iPhone 4 jailbreak code, which unlocks the iOS and lets users customize their phones, could leave the devices vulnerable to attack via downloaded PDF.

"iPhone users should be cautious when browsing unsolicited or suspicious websites, even if they haven't jailbroken their device," Symantec said in a statement.
