CVE-2020-12695

The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.

GUPnP is an elegant, object-oriented open source framework for creating UPnP devices and control points, written in C using GObject and libsoup. The GUPnP API is intended to be easy to use, efficient and flexible. It provides the same set of features as libupnp,but shields the developer from most of UPnP's internals.

Security Fix(es):

GSSDP implements resource discovery and announcement over SSDP and is part of gUPnP.

The following packages have been upgraded to a later upstream version: gssdp (1.0.5), gupnp (1.0.6). (BZ#1846589, BZ#1861928)

Security Fix(es):

The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue. (CVE-2020-12695).

It was discovered that minidlna does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue (CVE-2020-12695).

Minidlna before versions 1.3.0 allows remote code execution. Sending a malicious UPnP HTTP request to the miniDLNA service using HTTP chunked encoding can lead to a signedness bug resulting in a buffer overflow in calls to memcpy/memmove (CVE-2020-28926).

This update for minidlna fixes the following issues:

minidlna was updated to version 1.3.0 (boo#1179447)

• Fixed some build warnings when building with musl.
• Use $USER instead of $LOGNAME for the default friendly name.
• Fixed build with GCC 10
• Fixed some warnings from newer compilers
• Disallow negative HTTP chunk lengths. [CVE-2020-28926]
• Validate SUBSCRIBE callback URL. [CVE-2020-12695]
• Fixed spurious warnings with ogg coverart
• Fixed an issue with VLC where browse results would be truncated.
• Fixed bookmarks on Samsung Q series
• Added DSD file support.
• Fixed potential stack smash vulnerability in getsyshwaddr on macOS.
• Will now reload the log file on SIGHUP.
• Worked around bad SearchCriteria from the Control4 Android app.
• Increased max supported network addresses to 8.
• Added forced alphasort capability.
• Added episode season and number metadata support.
• Enabled subtitles by default for unknown DLNA clients, and add enable_subtitles config option.
• Fixed discovery when connected to certain WiFi routers.
• Added FreeBSD kqueue support.
• Added the ability to set the group to run as.

It was discovered that ReadyMedia (MiniDLNA) allowed subscription requests with a delivery URL on a different network segment than the fully qualified event- subscription URL. An attacker could use this to hijack smart devices and cause denial of service attacks. (CVE-2020-12695)

It was discovered that ReadyMedia (MiniDLNA) allowed remote code execution. A remote attacker could send a malicious UPnP HTTP request to the service using HTTP chunked encoding and cause a denial of service. (CVE-2020-28926)

It was discovered that wpa_supplicant did not properly handle P2P (Wi-Fi Direct) group information in some situations, leading to a heap overflow. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-0326)

It was discovered that hostapd did not properly handle UPnP subscribe messages in some circumstances. An attacker could use this to cause a denial of service. (CVE-2020-12695)
