Heap-based buffer underflow in the readPostBody function in cgiutil.c in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to have an unknown impact via a negative value in the Content-Length HTTP header.
Directory traversal vulnerability in mapserv.c in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2, when running on Windows with Cygwin, allows remote attackers to create arbitrary files via a .. (dot dot) in the id parameter.
mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to read arbitrary invalid .map files via a full pathname in the map parameter, which triggers the display of partial file contents within an error message, as demonstrated by a /tmp/sekrut.map symlink.
The msLoadQuery function in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 allows remote attackers to determine the existence of arbitrary files via a full pathname in the queryfile parameter, which triggers different error messages depending on whether this pathname exists.
mapserv.c in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 does not ensure that the string holding the id parameter ends in a '\0' character, which allows remote attackers to conduct buffer-overflow attacks or have unspecified other impact via a long id parameter in a query action.
Multiple stack-based buffer overflows in maptemplate.c in mapserv in MapServer 4.x before 4.10.4 and 5.x before 5.2.2 have unknown impact and remote attack vectors.
