USN-2364-1: Bash vulnerabilities

Florian Weimer and Todd Sabin discovered that the Bash parser incorrectly handled memory. An attacker could possibly use this issue to bypass certain environment restrictions and execute arbitrary code. CVE-2014-7186, CVE-2014-7187 In addition, this update introduces a hardening measure which add...

High risk warning: the Bash environment variables remote code insertion vulnerability-vulnerability warning-the black bar safety net

A few months ago around the high-profile OpenSSL heartbleed information disclosure vulnerability only in the past did not take long, the Internet also broke a than bleeding heart more fierce vulnerability: Bash environment variables remote code insertion vulnerability. The server of the cgi...

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 code or cause a denial of service uninitialized memory access, and untrusted-pointer read and write operations via a crafted...

“Broken shell vulnerability”of self-diagnosis and repair-vulnerability warning-the black bar safety net

”The broken shell vulnerability”of self-diagnosis and repair now is hot of the Bash vulnerability, also known as the”broken shell vulnerability”that can lead to a remote attacker on the affected system to execute arbitrary code, it can affect multiple System Services: Web, ssh, gitlab, DHCP, and ...

bash -- remote code execution

Note that this is different than the public "Shellshock" issue. Specially crafted environment variables could lead to remote arbitrary code execution. This was fixed in bash 4.3.27, however the port was patched with a mitigation in 4.3.252...

Apple — Most Mac OS X Users Not Vulnerable to 'Shellshock' Bash Bug

On one hand where more than half of the Internet is considering the Bash vulnerability to be severe, Apple says the vast majority of Mac computer users are not at risk from the recently discovered vulnerability in the Bash command-line interpreter – aka the "Shellshock" bug that could allow hacke...

bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)

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...

bash: parser can allow out-of-bounds memory access while handling redir_stack

It was identified that the fixed-sized redirstack could be forced to overflow in the Bash parser, resulting in memory corruption, and possibly leading to arbitrary code execution when evaluating untrusted input that would not otherwise be run as code...

bash: off-by-one error in deeply nested flow control constructs

An off-by-one error was discovered in the way Bash was handling deeply nested flow control constructs. Depending on the layout of the .bss segment, this could allow arbitrary execution of code that would not otherwise be executed by Bash...

Hackers Using 'Shellshock' Bash Vulnerability to Launch Botnet Attacks

Researchers on Thursday discovered a critical remotely exploitable vulnerability in the widely used command-line shell GNU Bourne Again Shell Bash, dubbed "Shellshock" which affects most of the Linux distributions and servers worldwide, and may already have been exploited in the wild to take over...
