Kevin Backhouse discovered that GDM incorrectly launched the initial setup tool when the accountsservice daemon was not reachable. A local attacker able to cause accountsservice to crash or stop responding could trick GDM into launching the initial setup tool and create a privileged user (CVE-2020-16125).

Mageia 2021-0001: audacity security update

Audacity through 2.3.3 saves temporary files to /var/tmp/audacity-$USER by default. After Audacity creates the temporary directory, it sets its permissions to 755. Any user on the system can read and play the temporary audio .au files located there (CVE-2020-11867).

Mageia 2020-0482: curl security update

Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data. (CVE-2020-8231). A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way

Mageia 2020-0480: flac security update

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

In FLAC__bitreader_read_rice_signed_block of bitreader.c, there is a possible out of bounds read due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation (CVE-2020-0499).

Mageia 2020-0478: openjpeg2 security update

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

There's a flaw in openjpeg in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability (CVE-2020-27841).

Mageia 2020-0476: jackit security update

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

posix/JackSocket.cpp in libjack in JACK2 1.9.1 through 1.9.12 has a "double file descriptor close" issue during a failed connection attempt when jackd2 is not running. Exploitation success depends on multithreaded timing of that double close, which can result in unintended information disclosure, crashes, or file corruption due to having the wrong file associated with the file

Mageia 2020-0475: kdeconnect-kde security update

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

For the pairing procedure, the GUI component only presented the friendly 'deviceName' to identify peer devices, which is completely under attacker control. Furthermore the 'deviceName' is transmitted in cleartext in UDP broadcast messages for all other nodes in the network segment to see. Therefore malicious devices can attempt to confuse users by requesting a

Mageia 2020-0473: libvirt security update

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

A double free memory issue was found to occur in the libvirt API responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or
