CVSS: 8.1EPSS: 21%CPEs: 6EXPL: 0CVE-2022-24903 – Buffer overflow in TCP syslog server (receiver) components in rsyslog
https://notcve.org/view.php?id=CVE-2022-24903
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 https://github.com/rsyslog/rsyslog/security/advisories/GHSA-ggw7-xr6h-mmr8 https://lists.debian.org/debian-lts-announce/2022/05/msg00028.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GMNNXLCU2UORRVSZO24HL4KMVPK5PHVW https://security.netapp.com/advisory/ntap-20221111-0002 https://www.debian.org/security/2022/dsa-5150 https://access.redhat.com/security/cve/CVE-2022-24903 https://bug • 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 •
CVSS: 9.8EPSS: 0%CPEs: 6EXPL: 0CVE-2019-17042 – rsyslog: heap-based overflow in contrib/pmcisconames/pmcisconames.c
https://notcve.org/view.php?id=CVE-2019-17042
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 up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00032.html https://github.com/rsyslog/rsyslog/blob/v8-stable/ChangeLog https://github.com/rsyslog/rsyslog/pull/3883 https://lists.debian.org/debian-lts-announce/2021/11/msg00030.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KPNCHI7X2IEXRH6RYD6IDPR4PLB5RPC7 https://lists.fedoraproject.org/archives/list/package-announce%40lists& • CWE-20: Improper Input Validation CWE-122: Heap-based Buffer Overflow •

An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap overflow in the parser for AIX log messages.
