Descriptions
An issue was discovered in Apport before 2.20.4. In apport/ui.py, Apport reads the CrashDB field and it then evaluates the field as Python code if it begins with a "{". This allows remote attackers to execute arbitrary Python code.
Un problema fue descubierto en Apport en versiones anteriores a 2.20.4. En apport/ui.py, Apport lee el campo CashDB y después evalúa el campo como código Python si comienza con un "{". Esto permite a atacantes remotos ejecutar código Python arbitrario.
Donncha O Cearbhaill discovered that the crash file parser in Apport improperly treated the CrashDB field as python code. 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. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. 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. Various other issues were also addressed.
