Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Multiple integer overflows in src/image.c in Ziproxy before 3.0.1 allow remote attackers to execute arbitrary code via (1) a large JPG image, related to the jpg2bitmap function or (2) a large PNG image, related to the png2bitmap function, leading to heap-based buffer overflows.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Integer overflows in Ziproxy's image.c (jpg2bitmap and png2bitmap functions) allow remote attackers to execute arbitrary code via crafted large JPG/PNG images, causing heap-based buffer overflows due to insufficient bounds checking when calculating bitmap dimensions.

MitigationUpgrade to Ziproxy 3.0.1 or later which contains bounds checking fixes; if upgrade is not immediately feasible, consider disabling or restricting the image transcoding features to reduce attack surface.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Ziproxy is installed
    Check for the Ziproxy binary or service: run 'which ziproxy' or look for /usr/sbin/ziproxy, /etc/ziproxy.conf, or check running processes with 'ps aux | grep ziproxy'
    Affected if Ziproxy is not installed on the system
  2. Determine installed Ziproxy version
    Run 'ziproxy -v' or 'ziproxy -V' to display version information, or check the package manager (dpkg -l ziproxy, rpm -qi ziproxy)
    Affected if The version is <= 3.0.0 or exactly matches any of these: 1.1, 1.2, 1.3, 1.4.0, 1.5.0, 1.5.1, 1.5.2, 1.9.0, 2.0.0, 2.1.0, 2.1.1
  3. Confirm image transcoding is enabled
    Inspect the Ziproxy configuration file (typically /etc/ziproxy.conf) for EnableConverters, Converters, or image-related directives that enable JPG/PNG transcoding
    Affected if Image conversion features for JPG or PNG are enabled in the configuration (the vulnerable jpg2bitmap and png2bitmap functions would be in use)

The system is affected if Ziproxy is installed with a version matching the affected ranges AND image transcoding (JPG/PNG conversion) is enabled, as the integer overflow flaw resides specifically in those conversion functions.
