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.

Buffer overflow in pamtofits of NetPBM 10.30 through 10.33 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code when assembling the header, possibly related to an off-by-one error.
