CVE-2026-40494 Apr 18, 01:42 CRITICAL PATCH Act Now

Heap buffer overflow in SAIL image library's TGA decoder allows remote code execution via malformed RLE-compressed TGA files against all versions prior to commit 45d48d1. Network-accessible applications processing untrusted TGA images can be fully compromised without authentication or user interaction (CVSS 9.8). The raw-packet RLE decompression path permits writing up to 496 bytes of attacker-controlled data beyond allocated heap bounds. Vendor patch confirmed via GitHub commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302. No CISA KEV listing or public POC identified at time of analysis, but the straightforward exploitation conditions (parsing untrusted files) and complete technical disclosure create high weaponization risk.

CVE-2026-40493 Apr 18, 01:41 CRITICAL Act Now

Heap buffer overflow in SAIL PSD codec allows remote code execution when processing malicious LAB-mode PSD files. Affects all SAIL versions prior to commit c930284 (HappySeaFox/sail). Attackers can achieve arbitrary code execution (CVSS 9.8: AV:N/AC:L/PR:N/UI:N) by triggering a mismatch between computed bytes-per-pixel (6 bytes for 3-channel 16-bit LAB) and allocated buffer size (5 bytes for BPP40_CIE_LAB format). Every pixel write deterministically overflows the heap buffer. EPSS data not available. Not listed in CISA KEV. Patch available via GitHub commit c930284445ea3ff94451ccd7a57c999eca3bc979.

CVE-2026-40492 Apr 18, 01:39 CRITICAL PATCH Act Now

Out-of-bounds memory access in SAIL image library's XWD codec allows remote attackers to achieve arbitrary code execution via malformed image files. The vulnerability stems from a pixel format mismatch where buffer allocation uses pixmap_depth=8 (1 byte/pixel) but byte-swap operations use bits_per_pixel=32 (4 bytes/pixel), causing 4x buffer overrun. CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) indicates trivial exploitation requiring only delivery of a crafted XWD file. EPSS data unavailable; no KEV listing indicates targeted rather than widespread exploitation. Fix available in commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02.
