Weekly CVE digest
One email a week with newly published vulnerabilities worth knowing about. No account needed.
This digest covers new vulnerabilities in general, not your servers. If you want to know which of them actually run in your infrastructure, that is what Secvalis does: it scans your machines and reports only what concerns them.
A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.
A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.
A flaw was found in Python's urllib.parse module where the urlparse method does not sanitize input, allowing characters like ' ' and ' ' in the URL path. This can lead to CRLF injection attacks.
