Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: SAIL (open-source image decoding library) has a critical flaw in its PSD codec. <br>β οΈ **Consequences**: Inconsistent byte-per-pixel calculation vs. buffer allocation leads to **Heap Buffer Overflow**.β¦
π‘οΈ **CWE**: CWE-787 (Out-of-bounds Write). <br>π **Flaw**: The logic calculating bytes per pixel does not match the actual pixel buffer allocation size in the PSD encoder/decoder.β¦
π§ͺ **Public Exp?**: No specific PoC code is listed in the `pocs` array. <br>π **Status**: However, the vulnerability is confirmed via GitHub Advisory (GHSA-rcqx-gc76-r9mv).β¦
π **Self-Check**: <br>1. Scan for usage of **SAIL** library in your codebase. <br>2. Check if you process **PSD** (Photoshop) files. <br>3. Verify SAIL version against the fix commit hash. <br>4.β¦
β **Fixed?**: **Yes**. <br>π§ **Patch**: The vendor has released a fix. <br>π **Reference**: See commit `c930284445ea3ff94451ccd7a57c999eca3bc979` on GitHub. Update to the latest version immediately.
Q9What if no patch? (Workaround)
π§ **No Patch Workaround**: <br>1. **Disable PSD support**: If SAIL is used only for other formats, disable the PSD codec module. <br>2. **Input Validation**: Strictly validate file headers before passing to SAIL. <br>3.β¦
π₯ **Urgency**: **CRITICAL**. <br>π **Priority**: **P0**. <br>With CVSS High severity, Network access, and Low complexity, this is a high-risk vulnerability.β¦
