The VMware vSphere Replication installed on the remote host is version 5.1.x prior to 5.1.2.2, 5.5.x prior to 5.5.1.3, 5.6.x prior to 5.6.0.2, or 5.8.x prior to 5.8.0.1. It is, therefore, affected by a command injection vulnerability in GNU Bash known as Shellshock, which is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system

The remote ASA Next-Generation Firewall (NGFW) host is missing a security patch. It is, therefore, affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.

Updated bash packages fix security vulnerability :

A flaw was found in the way Bash evaluated certain specially crafted environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue (CVE-2014-6271).

This vulnerability can be exposed and exploited through several other pieces of software and should be considered highly critical. Please refer to the RedHat Knowledge Base article and blog post for more information.

It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. An attacker could potentially use this flaw to override or bypass environment restrictions to execute shell commands. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue (CVE-2014-7169).

Bash has been updated to version 4.2 patch level 50, which further mitigates ShellShock-type vulnerabilities. Two such issues have already been discovered (CVE-2014-6277, CVE-2014-6278).

See the RedHat article on the backward-incompatible changes introduced by the latest patch, caused by adding prefixes and suffixes to the variable names used for exporting functions. Note that the RedHat article mentions these variable names will have parentheses '()' at the end of their names, however, the latest upstream patch uses two percent signs '%%' at the end instead.

Two other unrelated security issues in the parser have also been fixed in this update (CVE-2014-7186, CVE-2014-7187).

All users and sysadmins are advised to update their bash package immediately.

The remote IBM Storwize V7000 Unified device is running version 1.3.x prior to 1.4.3.5 or 1.5.x prior to 1.5.0.4. It is, therefore, affected by the following vulnerabilities :

  - A command injection vulnerability exists in GNU Bash     known as Shellshock. The vulnerability is due to the     processing of trailing strings after function     definitions in the values of environment variables.
    This allows a remote attacker to execute arbitrary code     via environment variable manipulation depending on the     configuration of the system. (CVE-2014-6271)   
  - An out-of-bounds memory access error exists in GNU Bash     in file parse.y due to evaluating untrusted input during     stacked redirects handling. A remote attacker can exploit     this, via a crafted 'here' document, to execute arbitrary     code or cause a denial of service. (CVE-2014-7186)

  - An off-by-one error exists in GNU Bash in the     read_token_word() function in file parse.y when handling     deeply-nested flow control constructs. A remote attacker     can exploit this, by using deeply nested loops, to     execute arbitrary code or cause a denial of service.
    (CVE-2014-7187)

  - A command injection vulnerability exists in GNU Bash     known as Shellshock. The vulnerability is due to the     processing of trailing strings after function     definitions in the values of environment variables.
    This allows a remote attacker to execute arbitrary code     via environment variable manipulation depending on the     configuration of the system. (CVE-2014-6278) Note that     this vulnerability exists because of an incomplete fix     for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277.
