Security researchers at Microsoft have unveiled details of two critical and important zero-day vulnerabilities that had recently been discovered after someone uploaded a malicious PDF file to VirusTotal, and get patched before being used in the wild . In late March, researchers at ESET found a malicious PDF file on VirusTotal, which they shared with the security team at Microsoft "as a potential exploit for an unknown Windows kernel vulnerability." After analyzing the malicious PDF file, the Microsoft team found that the same file includes two different zero-day exploits—one for Adobe Acrobat and Reader, and the other targeting Microsoft Windows. Since the patches for both the vulnerabilities were released in the second week of May, Microsoft released details of both the vulnerabilities today, after giving users enough time to update their vulnerable operating systems and Adobe software. According to the researchers, the malicious PDF including both the zero-days e...

Adobe has missed dozens of vulnerabilities in Reader in this week’s Patch Tuesday run according to Google engineers who reported the flaws. Sixteen vulnerabilities still affected the Windows and Mac OS X versions, while 31 critical and “trivially exploitable” bugs were found in the Linux application. Of particular concern to Google’s Mateusz Jurczyk and Gynvael Coldwind are bugs in Reader for Linux, although other issues affect versions for Windows and OS X. For the Linux version, which went completely unpatched, Adobe and Google have been working together to counter 14 “new unique crashes” and nine “test-cases” that were potentially exploitable for remote code execution. When Adobe released a new version of Reader for Windows and Mac OS X earlier this week, it patched 12 vulnerabilities, but another 16 remained unpatched. Jurczyk and Coldwind decided to come forward with information on those flaws in the interest of user safety, as Adobe has no plans to issue additional out of band ...

FireEye researchers recently came across a zero-day security flaw in Adobe Reader that's being actively exploited in the wild. The zero-day vulnerability is in Adobe PDF Reader 9.5.3, 10.1.5, 11.0.1 and earlier versions. According to researchers, once malware takes advantage of the flaw, its payload drops two dynamic-link libraries, or DLLs, which are application extensions used by executable files to perform a task. In this case, they allow the infected computer to communicate with a hacker-owned server. No additional details about the zero-day vulnerabilities have been publicly released, and but researchers with antivirus provider Kaspersky Lab have confirmed the exploit can successfully escape the Adobe sandbox. " We have already submitted the sample to the Adobe security team. Before we get confirmation from Adobe and a mitigation plan is available, we suggest that you not open any unknown PDF files ," said FireEye team. But until the vulnerability gets patched,...

Group-IB , a Russian cybercrime investigation company has discovered a zero-day vulnerability, affects Adobe Reader X and Adobe Reader XI. The vulnerability is also included in new modified version of Blackhole Exploit-Kit , which is used for the distributing the banking Trojans (Zeus, Spyeye, Carberp, Citadel) with the help of exploitation different vulnerabilities in client-side software. The particular exploit is available in underground forums for as much as $50,000 and bug is dangerous because it permits cybercriminals to run arbitrary shellcode by bypassing the sandbox feature integrated into the more recent versions of Adobe Reader. For now this flaw is distributed only in only small circles of the underground but it has the potential for much larger post-exploitation methods. The exploit is limited to  Microsoft Windows installations of Adobe Reader and it can’t be fully executed until the user closes his Web browser (...
