From 2.0.0 until 4.1.2, the TIFF CCITT Group 3 encoder allocates an undersized compressed-data buffer for narrow 1-bit images. TiffCcittCompressor.Initialize does not reserve enough space for the row data and T4 end-of-line codes, and T4BitCompressor.CompressStrip reaches unchecked writes when TiffCompression.CcittGroup3Fax is selected directly or inherited from decoded TIFF metadata. An attacker-controlled encode or decode-and-re-encode flow can write beyond the logical output span, corrupt process memory, and terminate the process. This issue is fixed in version 4.1.2.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-106110)\n\nAffected packages:\n\n- `SixLabors.ImageSharp >= 2.0.0, <= 4.1.1`\n\nPatched in:\n\n- `SixLabors.ImageSharp 4.1.2`\n\nSource: https://github.com/advisories/GHSA-j9gm-c75j-xc9q","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":220550,"id":"CVE-2026-106110","ts":1792022786347,"field":"exploit_available","old":"false","new":"true"}]}
