A write protection lock bit was left unset after boot on an older generation of Lenovo and IBM System x servers, potentially allowing an attacker with administrator access to modify the subset of flash memory containing Intel Server Platform Services (SPS) and the system Flash Descriptors.

In some Lenovo IdeaPad consumer notebook models, a race condition in the BIOS flash device locking mechanism is not adequately protected against, potentially allowing an attacker with administrator access to alter the contents of BIOS.

The IMM2 First Failure Data Capture function collects management module logs and diagnostic information when a hardware error is detected. This information is made available for download through an SFTP server hosted on the IMM2 management network interface. In versions earlier than 4.90 for Lenovo System x and earlier than 6.80 for IBM System x, the credentials to access the SFTP server are hard-coded and described in the IMM2 documentation, allowing an attacker with management network access to obtain the collected FFDC data. After applying the update, the IMM2 will create random SFTP credentials for use with OneCLI.

OpenSLP releases in the 1.0.2 and 1.1.0 code streams have a heap-related memory corruption issue which may manifest itself as a denial-of-service or a remote code-execution vulnerability.

An unprivileged attacker with connectivity to the IMM2 could cause a denial of service attack on the IMM2 (Versions earlier than 4.4 for Lenovo System x and earlier than 6.4 for IBM System x). Flooding the IMM2 with a high volume of authentication failures via the Common Information Model (CIM) used by LXCA and OneCLI and other tools can exhaust available system memory which can cause the IMM2 to reboot itself until the requests cease.

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

IBM System Networking G8052, G8124, G8124-E, G8124-ER, G8264, G8316, and G8264-T switches before 7.9.10.0; EN4093, EN4093R, CN4093, SI4093, EN2092, and G8264CS switches before 7.8.6.0; Flex System Interconnect Fabric before 7.8.6.0; 1G L2-7 SLB switch for Bladecenter before 21.0.21.0; 10G VFSM for Bladecenter before 7.8.14.0; 1:10G switch for Bladecenter before 7.4.8.0; 1G switch for Bladecenter before 5.3.5.0; Server Connectivity Module before 1.1.3.4; System Networking RackSwitch G8332 before 7.7.17.0; and System Networking RackSwitch G8000 before 7.1.7.0 have hardcoded credentials, which makes it easier for remote attackers to obtain access via unspecified vectors.
