Netpbm through 11.16.00 contains a heap out-of-bounds read vulnerability in rasttopnm that allows attackers to read heap memory by supplying Sun rasterfiles with short colormaps. Attackers can craft colormapped rasterfiles with pixel bytes exceeding the palette length to leak up to 255 adjacent heap bytes into the PNM output or crash the program.
Netpbm through 11.16.00 contains a heap out-of-bounds write vulnerability in the rasttopnm Sun rasterfile run-length decoder pr_load_image in converter/other/rast.c. Attackers can supply a byte-encoded rasterfile with tiny dimensions and a long run-length body to write controlled bytes past md_image, causing memory corruption and crashes.
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 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.
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.
Multiple buffer overflows in pnmtopng in netpbm 10.0 and earlier allow attackers to execute arbitrary code via a crafted PNM file.
Off-by-one buffer overflow in pnmtopng before 2.39, when using the -alpha command line option (Alphas_Of_Color), allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PNM file with exactly 256 colors.
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.
