An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached records for a given name to be updated to the Bogus DNSSEC validation state, instead of their actual DNSSEC Secure state, via a DNS ANY query. This results in a denial of service for installation that always validate (dnssec=validate),

Mageia 2020-0392: kernel security update

A flaw was found in the way the Linux kernel Bluetooth implementation handled L2CAP packets with A2MP CID. A remote attacker in adjacent range could use this flaw to crash the system causing denial of service or potentially execute arbitrary code on the system by sending a specially crafted L2CAP packet. The highest threat from this vulnerability is to data confidentiality and

Mageia 2020-0390: geary security update

GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail. (CVE-2020-24661)

Mageia 2020-0389: freetype2 security update

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

A heap buffer overflow has been found in freetype2 before 2.10.4. Malformed TTF files with PNG sbit glyphs can cause a heap buffer overflow in Load_SBit_Png as libpng uses the original 32-bit values, which are saved in png_struct. If the original width and/or height are greater than 65535, the allocated buffer won't be able to fit the

Mageia 2020-0388: tigervnc security update

In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception. (CVE-2020-26117)

Mageia 2020-0387: php security update

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

In PHP versions 7.2.x when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. (CVE-2020-7070)

Mageia 2020-0375: pdns security update

An issue has been found in PowerDNS Authoritative Server allowing an authorized user to cause the server to exit by inserting a crafted record in a MASTER type zone under their control. The issue is due to the fact that the Authoritative Server will exit when it runs into a parsing error while looking up the NS/A/AAAA records it is about to use for an outgoing notify
