CVE-2022-30595
Buffer over-flow in Pillow
Executive Summary
CVE-2022-30595 is a critical severity vulnerability affecting binary-analysis. It is classified as an undisclosed flaw. Ensure your systems and dependencies are patched immediately to mitigate exposure risks.
Precogs AI Insight
"The fundamental weakness here is traced back to within A TGA file, allowing the mishandling of memory allocation boundaries. In practice, this allows unauthorized actors to escalate their own privileges to administrative levels without proper credentials. Precogs identifies insecure dynamic linking patterns without requiring source code access to neutralize the threat at the source level."
What is this vulnerability?
CVE-2022-30595 is categorized as a critical Memory Corruption Vulnerability flaw. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.
When reading a TGA file with RLE packets that cross scan lines, Pillow reads the information past the end of the first line without deducting that from the.
This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Impact on Systems
✅ Remote Code Execution: Adversaries may execute arbitrary code by overwriting memory regions.
✅ Denial of Service: Memory corruption often leads to unrecoverable application crashes.
✅ Information Disclosure: Out-of-bounds reads can expose adjacent memory containing sensitive data.
How to fix this issue?
Implement the following strategic mitigations immediately to eliminate the attack surface.
1. Memory-Safe Languages When possible, migrate parsing logic to memory-safe languages like Rust or Go.
2. Compiler Protections Ensure the binary is compiled with ASLR, DEP/NX, Stack Canaries, and RELRO.
3. Fuzz Testing Implement continuous fuzzing with AddressSanitizer (ASan) in the CI/CD pipeline.
Vulnerability Signature
// Generic Memory Corruption Vector (C/C++)
void process_input(char *user_data, size_t size) \{
char buffer[256];
// DANGEROUS: Unbounded memory operation
memcpy(buffer, user_data, size); // size may exceed 256
// SECURED: Bound-checked operation
if (size \> sizeof(buffer)) \{
size = sizeof(buffer);
\}
memcpy(buffer, user_data, size);
\}

Attack Data Flow
| Stage | Detail |
|---|---|
| Source | Network packet or file input |
| Vector | Data exceeds the allocated buffer bounds during a copy operation |
| Sink | strcpy(), memcpy(), or pointer arithmetic |
| Impact | Memory corruption, Remote Code Execution (RCE) |
Vulnerable Code Pattern
// ❌ VULNERABLE: Memory Corruption
void process_data(char *input) {
char buffer[128];
// Taint sink: copies without bounds checking
strcpy(buffer, input);
}
Secure Code Pattern
// ✅ SECURE: Bounded Memory Operations
void process_data(char *input) {
char buffer[128];
// Sanitized boundary check
strncpy(buffer, input, sizeof(buffer) - 1);
buffer[sizeof(buffer) - 1] = '\0';
}
