Multiple format string vulnerabilities in the parse_error_msg function in parsehelp.c in dpkg before 1.17.22 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in the (1) package or (2) architecture name.
Weakness
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
