openssl1.0: Multiple issues (4.3)
Last modified: 2018-05-16 17:04:20 CEST
New Debian openssl1.0 1.0.2l-2+deb9u3 fixes: This update addresses the following issue: * Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. (CVE-2018-0739) CVE-2018-0739 openssl: Handling of crafted recursive ASN.1 structures can cause a stack overflow and resulting denial of service
