unbound: integer overflow in the regional allocator via the ALIGN_UP macro

Unbound before 1.9.5 allows an integer overflow in the regional allocator via the ALIGN_UP macro. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited

unbound: integer overflow in the regional allocator via regional_alloc

Unbound before 1.9.5 allows an integer overflow in the regional allocator via regional_alloc. NOTE: The vendor disputes that this is a vulnerability. Although the code may be vulnerable, a running Unbound installation cannot be remotely or locally exploited

unbound: configuration injection in create_unbound_ad_servers.sh upon a successful man-in-the-middle attack against a cleartext HTTP session

Unbound before 1.9.5 allows configuration injection in create_unbound_ad_servers.sh upon a successful man-in-the-middle attack against a cleartext HTTP session. NOTE: The vendor does not consider this a vulnerability of the Unbound software. create_unbound_ad_servers.sh is a contributed script from the community that facilitates automatic configuration creation. It is not part of the Unbound installation

Redmine before 3.4.13 and 4.x before 4.0.6 mishandles markup data during Textile formatting.

influxdb: authentication bypass because a JWT token may have an empty SharedSecret

InfluxDB before 1.7.6 has an authentication bypass vulnerability in the authenticate function in services/httpd/handler.go because a JWT token may have an empty SharedSecret (aka shared secret).

perl-dbi: NULL profile dereference in dbi_profile()

An issue was discovered in the DBI module before 1.643 for Perl. The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference.

An issue was discovered in InspIRCd 2 before 2.0.28 and 3 before 3.3.0. The mysql module contains a NULL pointer dereference when built against mariadb-connector-c 3.0.5 or newer. When combined with the sqlauth or sqloper modules, this vulnerability can be used for remote crashing of an InspIRCd server by any user able to connect to a server.

python-pip: directory traversal in _download_http_url() function in src/pip/_internal/download.py

The pip package before 19.2 for Python allows Directory Traversal when a URL is given in an install command, because a Content-Disposition header can have ../ in a filename, as demonstrated by overwriting the /root/.ssh/authorized_keys file. This occurs in _download_http_url in _internal/download.py.

libvncserver: unaligned accesses in hybiReadAndDecode can lead to a crash

An issue was discovered in LibVNCServer before 0.9.13. libvncserver/ws_decode.c can lead to a crash because of unaligned accesses in hybiReadAndDecode.

libvncserver: buffer overflow in ConnectClientToUnixSock()

libvncclient/sockets.c in LibVNCServer before 0.9.13 has a buffer overflow via a long socket filename.

kernel: net-sysfs: *_queue_add_kobject refcount issue

An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.

vim: users can execute arbitrary OS commands via scripting interfaces in the rvim restricted mode

In Vim before 8.1.0881, users can circumvent the rvim restricted mode and execute arbitrary OS commands via scripting interfaces (e.g., Python, Ruby, or Lua).

libvncserver: integer overflow and heap-based buffer overflow in libvncclient/cursor.c in HandleCursorShape function

libvncclient/cursor.c in LibVNCServer through 0.9.12 has a HandleCursorShape integer overflow and heap-based buffer overflow via a large height or width value. NOTE: this may overlap CVE-2019-15690.

usrsctp: Out of bounds reads in sctp_load_addresses_from_init()

usrsctp before 2019-12-20 has out-of-bounds reads in sctp_load_addresses_from_init.

libvirt: Potential DoS by holding a monitor job while querying QEMU guest-agent

qemu/qemu_driver.c in libvirt before 6.0.0 mishandles the holding of a monitor job during a query to a guest agent, which allows attackers to cause a denial of service (API blockage).

mod_auth_openidc: Open redirect issue exists in URLs with slash and backslash

A flaw was found in mod_auth_openidc before version 2.4.1. An open redirect issue exists in URLs with a slash and backslash at the beginning.

librsvg: Resource exhaustion via crafted SVG file with nested patterns

In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially.

exiv2: infinite loop and hang in Jp2Image::readMetadata() in jp2image.cpp could lead to DoS

In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.

libsolv: out-of-bounds read in repodata_schema2id in repodata.c

repodata_schema2id in repodata.c in libsolv before 0.7.6 has a heap-based buffer over-read via a last schema whose length is less than the length of the input schema.

QEMU: vnc: memory leakage upon disconnect

QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd.
