Last modified

CVE-2011-4623 is a vulnerability of currently unknown severity. Integer overflow in the rsCStrExtendBuf function in runtime/stringbuf.c in the imfile module in rsyslog 4.x before 4.6.6, 5.x before 5.7.4, and 6.x before 6.1.4 allows local users to cause a denial of service (daemon hang) via a large file, which triggers a heap-based buffer overflow.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
