GNU Bourne-Again Shell (Bash) Improper Restriction of Operations within the Bounds of a Memory BufferThe 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 unspecified other impact via crafted use of here documents, aka the "redir_stack" issue.

GNU Bourne-Again Shell (Bash) Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')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 oth… CWE-78Sep 27, 2014 | CVSS10.0v2.0 | EPSS64.3% | PoCs3 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX | |
CVE-2014-7169CRITICAL | GNU Bourne-Again Shell (Bash) Arbitrary Code Execution VulnerabilityGNU 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 occu… CWE-78Sep 25, 2014 | CVSS9.8v3.1 | EPSS>99.9% | PoCs21 | SignalsListed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
