CVSS: 10.0EPSS: 0%CPEs: 7EXPL: 0CVE-2022-24884 – Trivial signature forgery in ecdsautils
https://notcve.org/view.php?id=CVE-2022-24884
ecdsautils is a tiny collection of programs used for ECDSA (keygen, sign, verify). `ecdsa_verify_[prepare_]legacy()` does not check whether the signature values `r` and `s` are non-zero. A signature consisting only of zeroes is always considered valid, making it trivial to forge signatures. Requiring multiple signatures from different public keys does not mitigate the issue: `ecdsa_verify_list_legacy()` will accept an arbitrary number of such forged signatures. Both the `ecdsautil verify` CLI command and the libecdsautil library are affected. • https://github.com/freifunk-gluon/ecdsautils/commit/1d4b091abdf15ad7b2312535b5b95ad70f6dbd08 https://github.com/freifunk-gluon/ecdsautils/commit/39b6d0a77414fd41614953a0e185c4eefa2f88ad https://github.com/freifunk-gluon/ecdsautils/security/advisories/GHSA-qhcg-9ffp-78pw https://lists.debian.org/debian-lts-announce/2022/05/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4AKQH5WCBMJA3ODCSNERY6HVX4BX3ITG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messa • CWE-347: Improper Verification of Cryptographic Signature •

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 •

In OpenLDAP 2.x before 2.5.12 and 2.6.x before 2.6.2, a SQL injection vulnerability exists in the experimental back-sql backend to slapd, via a SQL statement within an LDAP query. This can occur during an LDAP search operation when the search filter is processed, due to a lack of proper escaping. En OpenLDAP versiones 2.x anteriores a 2.5.12 y versiones 2.6.x anteriores a 2.6.2, se presenta una vulnerabilidad de inyección SQL en el backend experimental back-sql de slapd, por medio de una sentencia SQL dentro de una consulta LDAP.
