Microsoft Windows PDF Library AES Encryption Out-Of-Bounds Read Information Disclosure Vulnerability

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Microsoft Windows PDF Library. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists...

OpenSSL AES-NI Padding Oracle MitM Information Disclosure

The remote host is affected by a man-in-the-middle MitM information disclosure vulnerability due to an error in the implementation of ciphersuites that use AES in CBC mode with HMAC-SHA1 or HMAC-SHA256. The implementation is specially written to use the AES acceleration available in x86/amd64...

CVE-2016-4437

Apache Shiro before 1.2.5, when a cipher key has not been configured for the “remember me” feature, allows remote attackers to execute arbitrary code or bypass intended access restrictions via an unspecified request parameter. Recent assessments: sv3nbeast at April 17, 2020 12:15pm UTC reported: ...

Apache Shiro v1.2.4 Cookie RememberME Deserial RCE

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache Shiro v1.2.4. Note that other versions of Apache Shiro may also be exploitable if the encryption key used by Shiro to encrypt rememberMe cookies is known. The gadget chain used for Java...

Petya Ransomware Installs Mischa As Failsafe

The Petya ransomware strain signaled a new escalation for crypto-malware when it surfaced in March. For the first time, ransomware went beyond encrypting files on local and shared drives and instead set its sights on locking up the Master File Table on compromised machines. Petya did have its...

openSUSE Security Update : openssl (openSUSE-2016-562)

This update for openssl fixes the following issues : - CVE-2016-2105: EVPEncodeUpdate overflow bsc977614 - CVE-2016-2106: EVPEncryptUpdate overflow bsc977615 - CVE-2016-2107: Padding oracle in AES-NI CBC MAC check bsc977616 - CVE-2016-2108: Memory corruption in the ASN.1 encoder bsc977617 -...

openssl: Padding oracle in AES-NI CBC MAC check

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by...

Locky Gets Clever!

As discussed in an earlier FireEye blog, we have seen Locky ransomware rise to fame in recent months. Locky is aggressively distributed via a JavaScript-based downloader sent as an attachment in spam emails, and may have overshadowed the Dridex banking Trojan as the top spam contributor. FireEye...

OpenSSL Padding Oracle Information Disclosure (CVE-2016-2107)

An information disclosure vulnerability exists in the AES-NI implementation of OpenSSL. The vulnerability is due to memory allocation miscalculation during a certain padding check. A remote attacker can exploit this vulnerability to obtain sensitive cleartext information via a padding-oracle atta...
