EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under CISA-ADP (Vulnrichment) CVSS v3.1 (NVD's own analysis pending). EPSS exploit probability: 0.4% (31st percentile of EPSS-scored CVEs). 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).

A fix is available — apply it.

Imager versions before 1.037 for Perl exit the process reading a raw image with an out-of-range raw_datachannels value in i_readraw_wiol.

Nothing range-checks raw_datachannels. The line buffer is sized as the image width times the channel count with no overflow check, so a negative or very large count requests an excessive allocation. When it fails, Imager's allocator calls exit(3).

Passing an untrusted raw_datachannels value to Imager->read() triggers an uncatchable exit.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
