ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the PostScript decoder, which allocates a buffer one byte longer than the data it decoded. Attackers can supply a crafted PostScript file to expose a single uninitialized byte of memory contents.

Data Freshness Timeline
(refreshed 10× in last 7d / 10× in last 30d)
Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures).
