Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process
A vulnerability in the handling of normalization with modrdn was discovered in OpenLDAP. An unauthenticated remote attacker can use this flaw to cause a denial of service (slapd daemon crash) via a specially crafted packet (CVE-2020-25692).
It was discovered that Docker could be made to expose sensitive information when processing URLs in container image manifests. A remote attacker could use this to trick the user and obtain the user's registry credentials (CVE-2020-15157).
SFD_GetFontMetaData() insufficient CVE-2020-5395 backport. (CVE-2020-25690) References: - https://bugs.mageia.org/show_bug.cgi?id=27563 - https://access.redhat.com/errata/RHSA-2020:4844
The latest release of mariadb fixes some undisclosed easily exploitable vulnerabilities. (CVE-2020-14765, CVE-2020-14776, CVE-2020-14789 and CVE-2020-14812). Additionally some bugs are fixed:
It was discovered that junit contained a local information disclosure vulnerability. On Unix like systems, the system's temporary directory is shared between all users on that system. Because of this, when files and directories are written into this directory they are, by default, readable by other users on that same system. This vulnerability does not allow other users
Vaisha Bernard discovered that blueman did not properly sanitize input on the D-Bus interface to blueman-mechanism. A local attacker could possibly use this issue to escalate privileges and run arbitrary code or cause a denial of service (CVE-2020-15238).
The suricata package has been updated to version 4.1.9, which fixes security issues and other bugs. See the upstream announcements for details. References: - https://bugs.mageia.org/show_bug.cgi?id=27475
An XSS Vulnerability exists in Webmin 1.941 and earlier affecting the Cluster Shell Commands Endpoint. A user may enter any XSS Payload into the Command field and execute it. Then, after revisiting the Cluster Shell Commands Menu, the XSS Payload will be rendered and executed. (CVE-2020-8820)
url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header. (CVE-2020-26154) References:
The implementation of realpath in libuv before 1.39 incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes (CVE-2020-8252). References:
If an HTTP/2 client exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected
Memory safety bugs fixed in Thunderbird 78.4. (CVE-2020-15683) Use-after-free in usersctp. (CVE-2020-15969) References:
Mozilla developers and community members Jason Kratzer, Simon Giesecke, Philipp, and Christian Holler reported memory safety bugs present in Firefox ESR 78.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code (CVE-2020-15683).
Shielded template's |program{} and |attach_program{} so that the command-line that is executed does not allow sequencing such as with && || ;, preventing possible execution of nasty, or at least unexpected, commands. (No CVE).
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),
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
In imap_scan_tree_recursive in Claws Mail through 3.17.6, a malicious IMAP server can trigger stack consumption because of unlimited recursion into subdirectories during a rebuild of the folder tree (CVE-2020-16094). References:
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)
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
