libssh2 through 1.11.1, fixed in commit 2dae302, contains an out-of-bounds heap read vulnerability in the sftpsymlink function in src/sftp.c that allows a malicious SSH server or man-in-the-middle attacker to disclose heap memory contents or cause a crash by sending a crafted SSHFXPNAME response...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

libssh2: libssh2: Information disclosure and denial of service via crafted SFTP response

A flaw in libssh2's sftpsymlink function allows a malicious SSH server or man-in-the-middle attacker to trigger an out-of-bounds heap read via a crafted SSHFXPNAME response. This can disclose heap memory contents or crash the application, causing a denial of service DoS...

MiracleLinux 8 : systemd-239-82.el8 (AXSA:2024-8329:02)

The remote MiracleLinux 8 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2024-8329:02 advisory. systemd-resolved: Unsigned name response in signed zone is not refused when DNSSEC=yes CVE-2023-7008 Tenable has extracted the preceding description block...

CVE-2025-32743

In ConnMan through 1.44, the lookup string in nsresolv in dnsproxy.c can be NULL or an empty string when the TC Truncated bit is set in a DNS response. This allows attackers to cause a denial of service application crash or possibly execute arbitrary code, because those lookup values lead to...

CVE-2023-7008 Systemd-resolved: unsigned name response in signed zone is not refused when dnssec=yes

A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles or the upstream DNS resolver to manipulate records...

The vulnerability of the QDnsLookup component of the cross-platform framework for Qt software development allows a hacker to induce a service failure.

The vulnerability of the QDnsLookup component of the cross-platform framework for Qt software development relates to reading data from beyond the allowable buffer size.
