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 the readImageData function in giftopnm.c in netpbm before 10.27 in netpbm before 10.27 allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted GIF image, a similar issue to CVE-2006-4484.

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.

Multiple buffer overflows in pnmtopng in netpbm 10.0 and earlier allow attackers to execute arbitrary code via a crafted PNM file.

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.

pstopnm in netpbm does not properly use the "-dSAFER" option when calling Ghostscript to convert a PostScript file into a (1) PBM, (2) PGM, or (3) PNM file, which allows external user-assisted attackers to execute arbitrary commands.

netpbm 9.25 and earlier does not properly create temporary files, which allows local users to overwrite arbitrary files.

Multiple vulnerabilities in NetPBM 9.20 and earlier, and possibly other versions, may allow remote attackers to cause a denial of service or execute arbitrary code via "maths overflow errors" such as (1) integer signedness errors or (2) integer overflows, which lead to buffer overflows.
