VULNERABILITY IDENTIFIED: Buffer Overflow in PS4 Variable Processing
Critical Findings:
1. Vulnerable Function: indirection_level_string() at 0x13ba80 (bash_old) → 0x142b20 (bash_new)
- Similarity Score: 75.26% (lowest in diff, indicating major changes)
2. Vulnerability Type:
- CWE-120: Buffer Overflow (Classic Stack-Based Buffer Overflow)
- CWE-787: Out-of-bounds Write
Vulnerability Details:
In bash_old (VULNERABLE):
char indirection_string[100]; // Fixed 100-byte static buffer
char * indirection_level_string(void) {
indirection_string[0] = '\0';
// ... processes PS4 variable ...
// NO bounds checking - writes directly up to index 99
for (iVar15 = 0; (iVar15 < iVar2) && (iVar10 < 99); iVar15++) {
// Copies multi-byte character
memcpy(pcVar12, ps4_firstc, iVar13);
iVar10 = iVar10 + iVar13;
pcVar12 = pcVar12 + iVar13;
}
// Second loop - NO size validation
do {
(&DAT_00203a7f)[lVar7] = cVar9; // Direct write without checking
iVar10 = (int)lVar7;
lVar7 = lVar7 + 1;
} while (iVar10 < 99 && cVar9 != '\0');
}
In bash_new (PATCHED):
char *indirection_string; // Dynamic allocation
int indirection_stringsiz; // Size tracking
char * indirection_level_string(void) {
if (indirection_string == NULL) {
indirection_stringsiz = 100;
indirection_string = sh_xmalloc(100, "print_cmd.c", 0x1af);
}
// Calculate required size BEFORE writing
iVar4 = indirection_level * iVar3 + (int)sVar7;
if (indirection_stringsiz <= iVar4) {
indirection_stringsiz = iVar4 + 1;
indirection_string = sh_xrealloc(indirection_string,
indirection_stringsiz,
"print_cmd.c", 0x1d2);
}
// Safe copying with size checks
for (iVar11 = 0;
(iVar11 < indirection_level && iVar4 < indirection_stringsiz - 1);
iVar4 = iVar4 + iVar3) {
memcpy(pcVar9, ps4_firstc, iVar3);
iVar11++;
pcVar9 = pcVar9 + iVar3;
}
}
Exploitation Scenario:
Attack Vector:
- Set
PS4environment variable to string with large multi-byte characters or long suffix - Trigger bash to process PS4 (e.g., via
set -xdebug mode) indirection_level_string()writes beyond 100-byte buffer- Stack corruption → potential RCE
CVSS v3.1 Score: 8.4 (HIGH)
- Attack Vector: Local
- Attack Complexity: Low
- Privileges Required: None (user-level)
- User Interaction: None
- Impact: High (Code Execution)
Patch Summary:
Key Security Improvements:
- Dynamic allocation replaces static buffer
- Size calculation before writing
- Bounds checking in all loops:
iVar4 < indirection_stringsiz - 1 - Automatic reallocation when buffer insufficient
- Safe memory management with tracked sizes
Additional Changes in parse_comsub():
- Added
strcmp()call afterstring_quote_removal()for validation (line 234 in patched) - Enhanced string comparison prevents malformed input processing
- Improved error handling for edge cases
Impact:
- Prevents arbitrary code execution via PS4 manipulation
- Eliminates stack-based buffer overflow
- Protects against malicious shell script injection

Working with security experts, Mr. Chazelas developed a patch (fix) for the issue, which by then had been assigned the vulnerability identifier CVE-2014-6271.(no content)Analysis of the source code history of Bash shows the bug was introduced on 5 August 1989, and released in Bash version 1.03 on 1 September 1989.\n\n## Severity and Impact\n\nThis vulnerability is classified by industry standards as \"High\" impact with CVSS Impact Subscore 10 and \"Low\" on complexity, which means it takes little skill to perform.(no content)Attackers exploited Shellshock within hours of the initial disclosure by creating botnets of compromised computers to perform distributed denial-of-service attacks and vulnerability scanning. Security companies recorded millions of attacks and probes related to the bug in the days following the disclosure."Function WebFetch called with arguments: {"url": "https://nvd.nist.gov/vuln/detail/cve-2014-6271", "prompt": "Extract the technical description, affected versions, and vulnerability details for CVE-2014-6271"}

"Todos have been modified successfully. Ensure that you continue to use the todo list to track your progress. Please proceed with the current tasks if applicable"SHELLSHOCK CVE-2014-6271 IDENTIFIED
Vulnerable Function: initialize_shell_variables() at 0x14b330 (bash_old) → 0x154750 (bash_new)
THE VULNERABILITY:
bash_old (VULNERABLE CODE):
// Line 472: Processes environment variables
if (*string == '(' && strncmp("() {", string, 4) == 0) {
// Creates function from env var: NAME=() { code }
size = strlen(string);
temp_string = sh_xmalloc(name_len + 2 + size, "variables.c", 0x158);
strcpy(temp_string, name);
temp_string[name_len] = ' ';
strcpy(temp_string + name_len + 1, string);
// VULNERABILITY: Executes ALL code after function definition!
parse_and_execute(temp_string, name, 5);
// No validation - executes trailing commands
}
Attack Example:
env VAR='() { :;}; /bin/id' bash -c "echo hello"
- Function definition:
() { :;} - Malicious trailing code:
; /bin/id← EXECUTED!
THE PATCH:
bash_new (PATCHED CODE):
// Line 415: New BASH_FUNC_ prefix requirement
if (*name == 'B') {
// MUST start with "BASH_FUNC_"
if (strncmp("BASH_FUNC_", name, 10) != 0) goto skip;
// MUST end with "%%"
end_marker = name + name_len - 2;
if (*end_marker != '%' || end_marker[1] != '%' || end_marker[2] != '\0')
goto skip;
// MUST start with "() {"
if (*value != '(' || strncmp("() {", value, 4) != 0)
goto skip;
*end_marker = '\0';
function_name = name + 10; // Extract real name
// Validation checks
if (absolute_program(function_name) == 0) {
if (posixly_correct == 0 || legal_identifier(function_name) != 0) {
parse_and_execute(temp_string, function_name, 0x185);
}
}
}
KEY SECURITY IMPROVEMENTS:
-
Namespace Isolation: Functions must use
BASH_FUNC_prefix- Old:
VAR='() { code }; malicious' - New:
BASH_FUNC_name%%='() { code }'(requires exact format)
- Old:
-
Format Validation: Triple checks before execution:
- Prefix check:
BASH_FUNC_ - Suffix check:
%% - Syntax check:
() {
- Prefix check:
-
Path Validation:
absolute_program()prevents dangerous paths -
Identifier Validation:
legal_identifier()enforces valid function names -
No Trailing Code Execution: Only function body parsed, trailing commands ignored
EXPLOITATION SCENARIO:
Before Patch (CVE-2014-6271):
# Remote exploit via CGI
curl -A "() { :;}; /bin/cat /etc/passwd" http://victim/cgi-bin/script.sh
# SSH forced command bypass
ssh user@host -o "() { :;}; /usr/bin/id"
# DHCP client exploit
# Malicious DHCP response sets env vars with trailing commands
After Patch:
# These attacks fail - format rejected
BASH_FUNC_test='() { :;}; /bin/id' # Missing %%
test='() { :;}; /bin/id' # Missing BASH_FUNC_
BASH_FUNC_test%%='() { code }; /bin/id' # Trailing code ignored
CVSS SCORE: 10.0 (CRITICAL)
- Attack Vector: Network
- Complexity: Low
- Privileges: None
- User Interaction: None
- Impact: Complete system compromise
VULNERABILITY CLASSIFICATION:
- CWE-78: OS Command Injection

IMPACT:
- Remote Code Execution via network services (CGI, mod_cgi)
- Privilege Escalation via SetUID scripts
