Buffer overflow in the French documentation patch for Gnuplot 3.7 in SuSE Linux before 8.0 allows local users to execute arbitrary code as root via unknown attack vectors.

An issue was discovered in datafile.c in Gnuplot 5.2.5. This issue allows an attacker to conduct a heap-based buffer overflow with an arbitrary amount of data in df_generate_ascii_array_entry. To exploit this vulnerability, an attacker must pass an overlong string as the right bound of the range argument that is passed to the plot function.

An issue was discovered in post.trm in Gnuplot 5.2.5. This issue allows an attacker to conduct a buffer overflow with an arbitrary amount of data in the PS_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 postscript terminal is used as a backend.

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.

A Divide by Zero vulnerability exists in gnuplot 5.4 in the boundary3d function in graph3d.c, which could cause a Arithmetic exception and application crash.

A flaw was found in gnuplot. The plot3d_points() function may lead to a segmentation fault and cause a system crash.

gnuplot is affected by a heap buffer overflow at function utf8_copy_one.

A flaw was found in gnuplot. The GetAnnotateString() function may lead to a segmentation fault and cause a system crash.

A flaw was found in gnuplot. The xstrftime() function may lead to a segmentation fault, causing a system crash.

A flaw was found in gnuplot. The CANVAS_text() function may lead to a segmentation fault and cause a system crash.

A flaw was found in gnuplot. The X11_graphics() function may lead to a segmentation fault and cause a system crash.
