Short explanation
An improper privilege management vulnerability in apport allows a local attacker to gain root privileges on systems with automatic crash reporting enabled [S0].
An unprivileged local attacker can gain root privileges and fully compromise affected systems [S0].
What should be done?
- Follow vendor advisories [S0].
Chain of evidence and sources
apport, otomatik hata raporu işleme sırasında ldd yürütülmesi nedeniyle yerel ayrıcalık yükseltmeye açıktır [S0].
Saldırganlar, ELF DT_AUDIT etiketi aracılığıyla rastgele kod çalıştırabilir ve sistemleri tamamen ele geçirebilir [S0].
Show the technical text from the sources
In apport before 2.37.0, an improper privilege management vulnerability allows an unprivileged local attacker to gain root privileges on systems where automatic crash reporting is enabled. The automatic crash report processing pipeline runs as root and executes ldd on the attacker-controlled ExecutablePath field of a crash file placed in the world-writable /var/crash directory, causing the dynamic loader to load and execute an attacker-supplied audit module specified by the ELF's DT_AUDIT tag. This allows an attacker to execute arbitrary code with root privileges and fully compromise the affected system.
