Security Vulnerabilities
- CVEs Published In April 2017
A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of service.
Riverbed RiOS through 9.6.0 deletes the secure vault with the rm program (not shred or srm), which makes it easier for physically proximate attackers to obtain sensitive information by reading raw disk blocks.
Riverbed RiOS through 9.6.0 does not require a bootloader password, which makes it easier for physically proximate attackers to defeat the secure-vault protection mechanism via a crafted boot. NOTE: the vendor believes that this does not meet the definition of a vulnerability. The product contains correct computational logic for a bootloader password; however, this password is optional to meet different customers' needs
Riverbed RiOS through 9.6.0 has a weak default password for the secure vault, which makes it easier for physically proximate attackers to defeat the secure-vault protection mechanism by leveraging knowledge of the password algorithm and the appliance serial number. NOTE: the vendor believes that this does not meet the definition of a vulnerability. The product contains correct computational logic for supporting arbitrary password changes by customers; however, a password change is optional to meet different customers' needs
Riverbed RiOS before 9.0.1 does not properly restrict shell access in single-user mode, which makes it easier for physically proximate attackers to obtain root privileges and access decrypted data by replacing the /opt/tms/bin/cli file.
The Go SSH library (x/crypto/ssh) by default does not verify host keys, facilitating man-in-the-middle attacks. Default behavior changed in commit e4e2799 to require explicitly registering a hostkey verification mechanism.
Privilege escalation in IntelHAXM.sys driver in the Intel Hardware Accelerated Execution Manager before version 6.0.6 allows a local user to gain system level access.
An issue (known as XSA-212) was discovered in Xen, with fixes available for 4.8.x, 4.7.x, 4.6.x, 4.5.x, and 4.4.x. The earlier XSA-29 fix introduced an insufficient check on XENMEM_exchange input, allowing the caller to drive hypervisor memory accesses outside of the guest provided input/output arrays.
D-Link DIR-615 HW: T1 FW:20.09 is vulnerable to Cross-Site Request Forgery (CSRF) vulnerability. This enables an attacker to perform an unwanted action on a wireless router for which the user/admin is currently authenticated, as demonstrated by changing the Security option from WPA2 to None, or changing the hiddenSSID parameter, SSID parameter, or a security-option password.
In Horde_Crypt before 2.7.6, as used in Horde Groupware Webmail Edition through 5.2.17, OS Command Injection can occur if the attacker is an authenticated Horde Webmail user, has PGP features enabled in their preferences, and attempts to encrypt an email addressed to a maliciously crafted email address.
