QEMU: use after free vulnerability in esp_do_dma() in hw/scsi/esp.c

A use-after-free vulnerability was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0 during the handling of the 'Information Transfer' command (CMD_TI). This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service or potential code execution with the privileges of the QEMU process.

QEMU: NULL pointer dereference in do_busid_cmd() in hw/scsi/esp.c

A NULL pointer dereference flaw was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0. This issue occurs while handling the 'Information Transfer' command. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

QEMU: NULL pointer dereference in scsi_req_continue() in hw/scsi/scsi-bus.c

A NULL pointer dereference flaw was found in the SCSI emulation support of QEMU in versions before 6.0.0. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

QEMU: NULL pointer dereference issue in megasas-gen2 host bus adapter

A NULL pointer dereference flaw was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU in versions before and including 6.0. This issue occurs in the megasas_command_cancelled() callback function while dropping a SCSI request. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

A flaw was found in Privoxy in versions before 3.0.29. Memory leaks when a response is buffered and the buffer limit is reached or Privoxy is running out of memory can lead to a system crash.

kernel: NULL pointer dereference in sco_sock_getsockopt function

A NULL pointer dereference flaw in Linux kernel versions prior to 5.11 may be seen if sco_sock_getsockopt function in net/bluetooth/sco.c do not have a sanity check for a socket connection, when using BT_SNDMTU/BT_RCVMTU for SCO sockets. This could allow a local attacker with a special user privilege to crash the system (DOS) or leak kernel internal information.

ovirt-engine: non-admin user is able to access other users public SSH key

A flaw was found in ovirt-engine 4.4.3 and earlier allowing an authenticated user to read other users' personal information, including name, email and public SSH key.

The contact-form-7 (aka Contact Form 7) plugin before 5.3.2 for WordPress allows Unrestricted File Upload and remote code execution because a filename may contain special characters.

The fileop module of the NXLog service in NXLog Community Edition 2.10.2150 allows remote attackers to cause a denial of service (daemon crash) via a crafted Syslog payload to the Syslog service. This attack requires a specific configuration. Also, the name of the directory created must use a Syslog field. (For example, on Linux it is not possible to create a .. directory. On Windows, it is not possible to create a CON directory.)

AnyDesk before 6.1.0 on Windows, when run in portable mode on a system where the attacker has write access to the application directory, allows this attacker to compromise a local user account via a read-only setting for a Trojan horse gcapi.dll file.

SolarWinds Serv-U before 15.2.2 allows authenticated reflected XSS.

SolarWinds Serv-U before 15.2.2 allows Unauthenticated Macro Injection.

mediawiki: divergent behavior for contributions and user pages of hidden users and missing users

An issue was discovered in MediaWiki before 1.35.1. Missing users (accounts that don't exist) and hidden users (accounts that have been explicitly hidden due to being abusive, or similar) that the viewer cannot see are handled differently, exposing sensitive information about the hidden status to unprivileged viewers. This exists on various code paths.

mediawiki: potential XSS via the month messages such as MediaWiki:january through MediaWiki:december outputting Block Logs

MediaWiki before 1.35.1 allows XSS via BlockLogFormatter.php. Language::translateBlockExpiry itself does not escape in all code paths. For example, the return of Language::userTimeAndDate is is always unsafe for HTML in a month value. This affects MediaWiki 1.12.0 and later.

mediawiki: potential XSS via MediaWiki:blanknamespace outputting Block Logs

MediaWiki before 1.35.1 allows XSS via BlockLogFormatter.php. MediaWiki:blanknamespace potentially can be output as raw HTML with SCRIPT tags via LogFormatter::makePageLink(). This affects MediaWiki 1.33.0 and later.

mediawiki: unable to change visibility of log entries when MediaWiki:Mainpage uses Special:MyLanguage

MediaWiki before 1.35.1 blocks legitimate attempts to hide log entries in some situations. If one sets MediaWiki:Mainpage to Special:MyLanguage/Main Page, visits a log entry on Special:Log, and toggles the "Change visibility of selected log entries" checkbox (or a tags checkbox) next to it, there is a redirection to the main page's action=historysubmit (instead of the desired behavior in which a revision-deletion form appears).

A remote code execution vulnerability occurs in OpenTSDB through 2.4.0 via command injection in the yrange parameter. The yrange value is written to a gnuplot file in the /tmp directory. This file is then executed via the mygnuplot.sh shell script. (tsd/GraphHandler.java attempted to prevent command injections by blocking backticks but this is insufficient.)

mediawiki: messages userrights-expiry-current and userrights-expiry-none can contain raw html

In MediaWiki before 1.35.1, the messages userrights-expiry-current and userrights-expiry-none can contain raw HTML. XSS can happen when a user visits Special:UserRights but does not have rights to change all userrights, and the table on the left side has unchangeable groups in it. (The right column with the changeable groups is not affected and is escaped correctly.)

mediawiki: message recentchanges-legend-watchlistexpiry can contain raw html

In MediaWiki before 1.35.1, the combination of Html::rawElement and Message::text leads to XSS because the definition of MediaWiki:recentchanges-legend-watchlistexpiry can be changed onwiki so that the output is raw HTML.

envoy: mishandling dropped and truncated datagrams leads to segfault and DoS

Envoy before 1.16.1 mishandles dropped and truncated datagrams, as demonstrated by a segmentation fault for a UDP packet size larger than 1500.
