Description

This security bulletin contains information about 1 vulnerability.


1) Heap-based buffer overflow (CVE-ID: CVE-2023-6246)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the __vsyslog_internal() function, which is called by both syslog() and vsyslog() while printing the SYSLOG_HEADER containing a long program name. A local user can pass a specially crafted input as arguments to the affected application, trigger a heap-based buffer overflow and execute arbitrary code on the system.
