CVE-2007-2721

Status: ModifiedMedium (4.3)—
The jpc_qcx_getcompparms function in jpc/jpc_cs.c for the JasPer JPEG-2000 library (libjasper) before 1.900 allows remote user-assisted attackers to cause a denial of service (crash) and possibly corrupt the heap via malformed image files, as originally demonstrated using imagemagick convert.
CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
Base score: 4.3
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.27%
Percentile among all scored CVEs: 83
Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
