systemd: stack overflow when calling syslog from a command with long cmdline

An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate privileges...

Denial Of Service (DoS)

libsystemd.so is vulnerable to denial of service DoS. When the syslog command is called with long cmdline input, an unlimited memory is allocated, which causes stack clashing with other memory space and crashes the application...

Important: systemd

Issue Overview: It was discovered that systemd-network does not correctly keep track of a buffer size when constructing DHCPv6 packets. This flaw may lead to an integer underflow that can be used to produce an heap-based buffer overflow. A malicious host on the same network segment as the victim'...

CVE-2018-16864

CVE-2018-16864 affects systemd-journald. The connected advisories confirm a memory-management issue in journald (and a backport memory leak in journald-server.c) that can crash journald or enable privilege escalation on local hosts. Root cause: memory allocations for command-line/state data not p...

New Systemd Privilege Escalation Flaws Affect Most Linux Distributions

Security researchers have discovered three vulnerabilities in Systemd, a popular init system and service manager for most Linux operating systems, that could allow unprivileged local attackers or malicious programs to gain root access on the targeted systems. The vulnerabilities, assigned as...
