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...

[SECURITY] Fedora 26 Update: glibc-2.25-13.fc26

The glibc package contains standard libraries which are used by multiple programs on the system. In order to save disk space and memory, as well as to make upgrading easier, common system code is kept in one place and shared between programs. This particular package contains the most important se...

CVE-2017-17426

The malloc function in the GNU C Library aka glibc or libc6 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZEMAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache aka tcache feature...
