Multiple integer overflows in xzgv 0.8 and earlier allow remote attackers to execute arbitrary code via images with large width and height values, which trigger a heap-based buffer overflow, as demonstrated in the read_prf_file function in readprf.c. NOTE: CVE-2004-0994 and CVE-2004-1095 identify sets of bugs that only partially overlap, despite having the same developer. Therefore, they should be regarded as distinct.

zgv 5.5.3 allows remote attackers to cause a denial of service (application crash via segmentation fault) via crafted multiple-image (animated) GIF images.

Multiple buffer overflows in the psscan function in ps.c for gv (ghostview) allow remote attackers to execute arbitrary code via a Postscript file with a long (1) BoundingBox, (2) comment, (3) Orientation, (4) PageOrder, or (5) Pages value.

gv 3.5.8, and possibly earlier versions, allows remote attackers to execute arbitrary commands via shell metacharacters in the filename for (1) a PDF file or (2) a gzip file.

Maped in LuxMan 0.41 uses the user-provided search path to find and execute the gzip program, which allows local users to modify /dev/mem and gain privileges via a modified PATH environment variable that points to a Trojan horse gzip program.

Buffer overflow in (1) gv 3.5.8 and earlier, (2) gvv 1.0.2 and earlier, (3) ggv 1.99.90 and earlier, (4) gnome-gv, and (5) kghostview in kdegraphics 2.2.2 and earlier, allows attackers to execute arbitrary code via a malformed (a) PDF or (b) PostScript file, which is processed by an unsafe call to sscanf.

gnatsweb.pl in GNATS GnatsWeb 2.7 through 3.95 allows remote attackers to execute arbitrary commands via certain characters in the help_file parameter.
