An out-of-bounds write vulnerability was found in netpbm before 10.61. A maliciously crafted file could cause the application to crash or possibly allow code execution.

An out-of-bounds read vulnerability was found in netpbm before 10.61. The expandCodeOntoStack() function has an insufficient code value check, so that a maliciously crafted file could cause the application to crash or possibly allows code execution.

Stack-based buffer overflow in converter/ppm/xpmtoppm.c in netpbm before 10.47.07 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an XPM image file that contains a crafted header field associated with a large color index value.

pamperspective in Netpbm before 10.35.48 does not properly calculate a window height, which allows context-dependent attackers to cause a denial of service (crash) via a crafted image file that triggers an out-of-bounds read.

pnmtopng in netpbm before 10.25, when using the -trans option, uses uninitialized size and index variables when converting Portable Anymap (PNM) images to Portable Network Graphics (PNG), which might allow attackers to execute arbitrary code by modifying the stack.
