CVSS: 8.1EPSS: 1%CPEs: 6EXPL: 0CVE-2022-24903 – Buffer overflow in TCP syslog server (receiver) components in rsyslog
https://notcve.org/view.php?id=CVE-2022-24903
05 May 2022 — Rsyslog is a rocket-fast system for log processing. Modules for TCP syslog reception have a potential heap buffer overflow when octet-counted framing is used. This can result in a segfault or some other malfunction. As of our understanding, this vulnerability can not be used for remote code execution. But there may still be a slight chance for experts to do that. • https://github.com/rsyslog/rsyslog/commit/f211042ecbb472f9d8beb4678a65d272b6f07705 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write CWE-1284: Improper Validation of Specified Quantity in Input •

07 Oct 2019 — An issue was discovered in Rsyslog v8.1908.0. contrib/pmcisconames/pmcisconames.c has a heap overflow in the parser for Cisco log messages. The parser tries to locate a log message delimiter (in this case, a space or a colon), but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat u... • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00031.html • CWE-20: Improper Input Validation CWE-122: Heap-based Buffer Overflow •

06 Aug 2017 — The zmq3 input and output modules in rsyslog before 8.28.0 interpreted description fields as format strings, possibly allowing a format string attack with unspecified impact. Los módulos de entrada y salida de zmq3 en versiones de rsyslog anteriores a 8.28.0 interpretaban campos de descripción como cadenas de formato, lo que podía dar lugar a un ataque de tipo “format string” y causar un impacto no especificado. • https://github.com/rsyslog/rsyslog/blob/master/ChangeLog • CWE-134: Use of Externally-Controlled Format String •
