CVE-2018-19492: n/a vulnerability

CVE-2018-19492: An issue was discovered in cairo.trm in Gnuplot 5.2.5.

An issue was discovered in cairo.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the cairotrm_options function. This flaw is caused by a missing size check of an argument passed to the "set font" function. This issue occurs when the Gnuplot pngcairo terminal is used as a backend.

Security readout for executives and security teams

CVE-2018-19492 is a memory-safety flaw in Gnuplot 5.2.5 when using the pngcairo terminal backend. A malicious or unsafe plotting input could trigger a buffer overflow through an oversized font setting. Business risk is mainly in automated report, chart, or document-generation systems that process untrusted Gnuplot scripts or data. Exposure is most likely where Gnuplot 5.2.5 or vulnerable distro packages render user-supplied or externally sourced plots through the pngcairo backend. Workstations using Gnuplot only on trusted local scripts are lower risk. Treat as a targeted patching priority for analytics, reporting, and conversion systems that process external input. It is not KEV-listed in the provided data, so urgency depends on exposure to untrusted plotting content. Mitigation focus: Apply fixed Gnuplot packages from Debian, Ubuntu, openSUSE, or your OS vendor.; Prioritize systems that render charts from user-supplied or external data.; Restrict untrusted Gnuplot scripts until patched..
