Donncha O Cearbhaill discovered that Apport did not properly sanitize the
Package and SourcePackage fields in crash files before processing package
specific hooks. An attacker could use this to convince a user to open a
maliciously crafted crash file and execute arbitrary code with the
privileges of that user. (CVE-2016-9950)

Donncha O Cearbhaill discovered that Apport would offer to restart an
application based on the contents of the RespawnCommand or ProcCmdline
fields in a crash file. An attacker could use this to convince a user to
open a maliciously crafted crash file and execute arbitrary code with the
privileges of that user. (CVE-2016-9951)");
