New! Plugin Severity Now Using CVSS v3
The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.
Synopsis
The remote Solaris system is missing a security patch for third party software.Description
The remote Solaris system is missing necessary patches to address critical security updates related to 'Shellshock' :- GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code 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, also known as 'Shellshock.' Note that the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix. (CVE-2014-6271)
- GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access, and untrusted-pointer read and write operations) 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 that this vulnerability exists because of an incomplete fix for CVE-2014-6271 and CVE-2014-7169. (CVE-2014-6277)
- GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands 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 that this vulnerability exists because of an incomplete fix for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277.
(CVE-2014-6278)
- 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 other unknown 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 that this vulnerability exists because of an incomplete fix for CVE-2014-6271. (CVE-2014-7169)
- The redirection implementation in 'parse.y' in GNU Bash through 4.3 bash43-026 allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have other unspecified impact via crafted use of 'here' documents, also known as the 'redir_stack' issue. (CVE-2014-7186)
- An off-by-one error in the 'read_token_word' function in 'parse.y' in GNU Bash through 4.3 bash43-026 allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have other unspecified impact via deeply nested for-loops, also known as the 'word_lineno' issue.
(CVE-2014-7187)
