alpine 3.6
access weakness #291


Weakness Breakdown


An access weakness occurs when software does not properly implement permissions that could have unintended consequences if exploited by malicious actors. An example of this weakness is when a default username and password are set by the developer but do not get changed by the system administrator.

Warning code(s):

Ensure that umask is given most restrictive possible setting.

The highlighted line of code below is the trigger point of this particular Alpine 3.6 access weakness.


** Main routine for translating composition file
** into valid MIME message.  It translates the draft
** into a content structure (actually a tree of content
** structures).  This message then can be manipulated
** in various ways, including being output via
** output_message().
static CT
build_mime(char *infile)
	enum state state;
	struct field f = {{0}};
	int compnum;
	char buf[BUFSIZ];
	char *cp, *np, *vp;
	struct multipart *m;
	struct part **pp;
	CT ct;
	FILE *in;
	HF hp;


	/* open the composition draft */
	if ((in = fopen(infile, "r")) == NULL) {
		adios(EX_IOERR, infile, "unable to open for reading");

	** Allocate space for primary (outside) content
	ct = mh_xcalloc(1, sizeof(*ct));

	** Allocate structure for handling decoded content
	** for this part.  We don't really need this, but
	** allocate it to remain consistent.

	** Parse some of the header fields in the composition
	** draft into the linked list of header fields for
	** the new MIME message.
