CVE-2026-70654

MEDIUMPre-NVD 5.85.8—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 98% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, applications that define unusual custom libvips sources and use them to process untrusted uncompressed PPM images can trigger a max/min error in vips_source_read_to_memory in libvips/iofuncs/source.c. The function uses VIPS_MAX instead of VIPS_MIN when selecting the remaining read size, allowing up to 4032 bytes to be written beyond the allocated heap buffer and causing memory corruption or a process crash. This issue is fixed in version 8.18.3.
