Affected component: libxml2’s xmlSchemaValidateStream; root cause relates to a lea...

CVE-2018-0735

CVE-2018-0735 corresponds to a timing side-channel vulnerability in OpenSSL’s ECDSA signature generation. An attacker could exploit variations in signing to recover the private key. Affected: OpenSSL 1.1.0 (1.1.0-1.1.0i) and OpenSSL 1.1.1 (1.1.1) prior to the fixes. Fixes were released in OpenSSL...

CVE-2021-3541

CVE-2021-3541 describes a vulnerability in libxml2 where exponential entity expansion can bypass protections and cause a denial of service. The Initial Description confirms the flaw and its DoS impact, and connected documents (e.g., Astra Linux bulletin and BSNSA entries) reiterate libxml2 involv...

CVE-2023-29552

CVE-2023-29552 describes a DoS vulnerability in the Service Location Protocol (SLP) where an unauthenticated remote attacker can register arbitrary services, causing SLP server to respond with spoofed traffic and enabling large amplification (reported up to ~2,200x). Documented impacts include po...

CVE-2022-23308

CVE-2022-23308 affects libxml2 before 2.9.13, caused by a use-after-free in ID/IDREF attributes in valid.c. The NVD data shows a CVSS 3.1 base score of 7.5 (NETWORK, PR:N, UI:N, S:U, C:N/I:N/A:H) and CVSS 2.0 base score of 4.3 (NETWORK, A:P). Connected advisories confirm the same flaw and referen...

CVE-2020-15862

CVE-2020-15862 affects Net-SNMP with an improper privilege management flaw: SNMP WRITE access to the EXTEND MIB allows an authenticated local attacker to execute arbitrary commands as root. Practical impact is local privilege escalation; exploitation requires access to an authenticated SNMP sessi...

CVE-2022-29824

Summary: CVE-2022-29824 affects libxml2 up to version 2.9.14. Several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) fail to check integer overflows, causing out-of-bounds memory writes when processing crafted XML files. This vulnerability also affects software that uses lib...

CVE-2022-40304

CVE-2022-40304: libxml2 before 2.10.3 contains invalid XML entity definitions that can corrupt a hash table key, potentially triggering logic errors and, in at least one case, a double-free. Affected library is libxml2; CVSS v3.1 shows base score 7.8 (HIGH) with LOCAL access, high impact. Public ...

CVE-2016-8610

CVE-2016-8610 is a denial-of-service flaw in OpenSSL affecting TLS/SSL alert packet processing during handshakes. The issue exists in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0, enabling a remote attacker to cause high CPU usage and denial of service by sending many alert messages. Con...

CVE-2022-1473

Summary: CVE-2022-1473 concerns a bug in the OPENSSL_LH_flush() function in OpenSSL 3.0 that breaks reuse of memory for removed hash table entries, used when decoding certificates or keys, leading to unbounded memory growth and potential DoS in long-lived processes (e.g., TLS clients/servers). Wh...
