A malicious PDF document that exploits bugs in Adobe's Reader and Acrobat software is on the loose, Symantec said Tuesday, just hours after Adobe patched the programs."This mass mailing of exploit files may be an attempt to leverage the exposure window between patch release and widespread adoption of the fix," said Symantec in a warning to customers of its DeepSight threat intelligence network.The rogue PDF document is attached to spammed e-mail and arrives with a filename like YOUR_BILL.pdf or INVOICE.pdf, said Symantec. It exploits the "mailto:" protocol vulnerability disclosed more than a month ago by U.K.-based researcher Petko Petkov.Adobe fixed the flaw Monday and released updated 8.1.1 editions of both Reader and Acrobat that plug the hole. Users of older versions of the popular programs must either upgrade to 8.1.1 or apply one of the temporary work-arounds Adobe provided to stifle attacks. On Monday, Adobe did say that it would update Adobe Reader 7.0.9 and Acrobat 7.0.9 "at a later date" but did not set a definitive timeline.When recipients open the attacking PDF, it launches a Trojan horse dubbed "Pidief.a" that knocks out the Windows firewall and then downloads another piece of malware to the compromised computer. That second piece of attack code is a dedicated downloader that can retrieve files from a remote server and, at the attacker's command, pull them onto the hacked PC."The host [server] is live and still currently serving [the downloader] over FTP," said Symantec this morning. The server is well known for hosting malicious software, the warning added.Although Adobe patched the newest versions of Reader and Acrobat, the vulnerability is ultimately Microsoft's responsibility. The software vendor owned up to that two weeks ago, saying that it would patch common protocol handlers like mailto: in Windows XP and Windows Server 2003.Only users running the Internet Explorer 7 browser on XP or Windows Server 2003 are vulnerable to the PDF exploit."[Users] are advised to apply the patches outlined in Adobe Advisory APSB07-18 as soon as possible," Symantec recommended.Computerworld is an InfoWorld affiliate

Adobe released on Wednesday an update that fixes vulnerabilities in its widely used Reader document viewing program.Users are urged to upgrade to version 8.1.2, available for download on Adobe&#39;s Web site.Adobe has not given out details of the vulnerabilities, even though the company has a section on its Web site detailing security advisories for Reader.That could indicate that the vulnerabilities are fairly serious and could result in a compromised PC, said Thomas Kristensen, chief technical officer for Secunia, a security vendor in Denmark.Secunia is performing a binary analysis of the old and new versions of Reader to figure out the vulnerabilities. However, that analysis takes one to three days, Kristensen said.Kristensen said no proof-of-concept code has been seen yet and no attacks have been reported. But people should be especially cautious of PDFs (Portable Document Format), the common file type that Reader opens.&quot;PDFs are generally highly trusted,&quot; Kristensen said. &quot;It&#39;s a common format for exchanging information.&quot;Secunia estimates that more than 60 percent of home PC users have the Reader program, based on data from one of its software products that checks to see if programs have up-to-date patches. Corporate use of Reader is less, around 30 percent, since many companies use other business applications that can open PDFs, Kristensen said.Hackers seized on PDFs&#160;last year after the disclosure of a&#160;protocol handling vulnerability involving Windows. The problem allowed them to create malicious PDF documents that would infect a PC with malicious software if opened.Adobe officials could not be reached.&#160;
