CVE-2017-7306

** DISPUTED ** 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.

CVE-2016-10318

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.

CVE-2017-5670

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.

CVE-2017-7305

** DISPUTED ** 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.

Red Hat Security Advisory 2017-0869-01

Red Hat Security Advisory 2017-0869-01 – The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). Enhancement:

CVE-2017-7414

In Horde_Crypt before 2.7.6, as used in Horde Groupware Webmail Edition 5.x through 5.2.17, OS Command Injection can occur if the user has PGP features enabled in the user’s preferences, and has enabled the “Should PGP signed messages be automatically verified when viewed?” preference. To exploit this vulnerability, an attacker can send a PGP signed email (that is maliciously crafted) to the Horde user, who then must either view or preview it.

CVE-2017-3204

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.

CVE-2017-7413

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.
