Two vulnerabilities were discovered in Libvirt, a virtualisation abstraction library, allowing an API client with read-only permissions to execute arbitrary commands via the virConnectGetDomainCapabilities API, or read or execute arbitrary files via the
A path traversal vulnerability due to an unsanitized POST parameter was discovered in php-horde-form, a package providing form rendering, validation, and other functionality for the Horde Application Framework. An attacker can take advantage of this flaw for remote code execution.
DSA 4447-1 shipped updated CPU microcode for most types of Intel CPUs as mitigations for the MSBDS, MFBDS, MLPDS and MDSUM hardware vulnerabilities. This update provides additional support for some Sandybridge server
User “Arminius” discovered a vulnerability in Vim, an enhanced version of the standard UNIX editor Vi (Vi IMproved). The “Common vulnerabilities and exposures project” identifies the following problem:
Samuel Gross discovered a type confusion bug in the JavaScript engine of the Mozilla Firefox web browser, which could result in the execution of arbitrary code when browsing a malicious website.
Multiple security issues have been found in Thunderbird which may lead to the execution of arbitrary code if malformed email messages are read. For the stable distribution (stretch), these problems have been fixed in
Two vulnerabilities were discovered in the ZNC IRC bouncer which could result in remote code execution (CVE-2019-12816) or denial of service via invalid encoding (CVE-2019-9917).
Joe Vennix discovered an authentication bypass vulnerability in dbus, an asynchronous inter-process communication system. The implementation of the DBUS_COOKIE_SHA1 authentication mechanism was susceptible to a symbolic link attack. A local attacker could take advantage of this flaw
Multiple security vulnerabilities have been discovered in MediaWiki, a website engine for collaborative work, which may result in authentication bypass, denial of service, cross-site scripting, information disclosure and bypass of anti-spam measures.
Multiple security issues were discovered in the VLC media player, which could result in the execution of arbitrary code or denial of service if a malformed file/stream is processed.
Harrison Neil discovered that the getACL() command in Zookeeper, a service for maintaining configuration information, did not validate permissions, which could result in information disclosure.
A flaw was discovered in the CalDAV feature in httpd of the Cyrus IMAP server, leading to denial of service or potentially the execution of arbitrary code via a crafted HTTP PUT operation for an event with a long iCalendar property name.
Hanno Böck discovered that Evolution was vulnerable to OpenPGP signatures being spoofed for arbitrary messages using a specially crafted HTML email. This issue was mitigated by moving the security bar with encryption and signature information above the message
Vincent Tondellier reported that the qemu update issued as DSA 4454-1 did not correctly backport the support to define the md-clear bit to allow mitigation of the MDS vulnerabilities. Updated qemu packages are now available to correct this issue.
The Qualys Research Labs reported a flaw in Exim, a mail transport agent. Improper validation of the recipient address in the deliver_message() function may result in the execution of arbitrary commands.
Several vulnerabilities were discovered in Heimdal, an implementation of Kerberos 5 that aims to be compatible with MIT Kerberos. CVE-2018-16860
Multiple security issues were discovered in QEMU, a fast processor emulator, which could result in denial of service, the execution of arbitrary code or information disclosure.
Several vulnerabilities have been discovered in OpenJDK, an implementation of the Oracle Java platform, resulting in denial of service or sandbox bypass.
Multiple security issues were found in jackson-databind, a Java library to parse JSON and other data formats which could result in information disclosure or the execution of arbitrary code.
Multiple security issues have been found in Thunderbird: Multiple vulnerabilities may lead to the execution of arbitrary code or denial of service.
A vulnerability was found in the WPA protocol implementation found in wpa_supplication (station) and hostapd (access point). The EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code. For the stable distribution (stretch), these problems have been fixed in
Several vulnerabilities have been discovered in the FFmpeg multimedia framework, which could result in denial of service or potentially the execution of arbitrary code if malformed files/streams are processed.
This update ships updated CPU microcode for most types of Intel CPUs. It provides mitigations for the MSBDS, MFBDS, MLPDS and MDSUM hardware vulnerabilities.
It was discovered that the Lemonldap::NG web SSO system performed insuffient validation of session tokens if the “tokenUseGlobalStorage” option is enabled, which could grant users with access to the main session database access to an anonymous session.
Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to
It was discovered that incomplete validation in a Phar processing library embedded in Drupal, a fully-featured content management framework, could result in information disclosure.
Isaac Boukris and Andrew Bartlett discovered that the S4U2Self Kerberos extension used in Samba’s Active Directory support was susceptible to man-in-the-middle attacks caused by incomplete checksum validation.
The update for ghostscript released as DSA 4442-1 uncovered an issue in cups-filters which was using the undocumented Ghostscript internal “pdfdict” now hidden in the ghostscript update. Updated cups-filters packages are now available to correct this issue.
A vulnerability was discovered in Ghostscript, the GPL PostScript/PDF interpreter, which may result in denial of service or the execution of arbitrary code if a malformed Postscript file is processed (despite the – -dSAFER sandbox being enabled).
