CVE-2015-1338
HighSummary
A vulnerability in kernel_crashdump in Apport before version 2.19 allows local users to cause a denial of service (disk consumption) or potentially gain privileges via a (1) symlink or (2) hard link attack on /var/crash/vmcore.log.
Risk Assessment
Organizations may be exposed to denial of service due to excessive disk space consumption, which can lead to system availability issues. There is also a risk of unauthorized privilege escalation by local users.
Recommendation
It is recommended to update Apport to the latest version to mitigate this vulnerability and to monitor the system for unauthorized activities related to the vmcore.log file.
