grafana: SSRF incorrect access control vulnerability allows unauthenticated users to make grafana send HTTP requests to any URL

The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.

QEMU: megasas: OOB read access due to invalid index leads to DoS

In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user.

QEMU: es1370: OOB access due to incorrect frame count leads to DoS

In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.

mariadb-connector-c: Improper validation of content in a OK packet received from server

libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for MySQL, this issue does not affect any MySQL components supported by Oracle.

wireshark: NFS dissector crash (wnpa-sec-2020-08)

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem.

kernel: usb: gadget: illegal array access in binding with UDC

gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel 3.16 through 5.6.13 relies on kstrdup without considering the possibility of an internal '\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.

libexif: unrestricted size in handling Canon EXIF MakerNote data can lead to consumption of large amounts of compute time

An issue was discovered in libexif before 0.6.22. An unrestricted size in handling Canon EXIF MakerNote data could lead to consumption of large amounts of compute time for decoding EXIF data.

libexif: use of uninitialized memory in EXIF Makernote handling can lead to crashes and use-after-free

An issue was discovered in libexif before 0.6.22. Use of uninitialized memory in EXIF Makernote handling could lead to crashes and potential use-after-free conditions.

libexif: several buffer over-reads in EXIF MakerNote handling can lead to information disclosure and DoS

An issue was discovered in libexif before 0.6.22. Several buffer over-reads in EXIF MakerNote handling could lead to information disclosure and crashes. This is different from CVE-2020-0093.

Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario

The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.

sane-backends: NULL pointer dereference in sanei_epson_net_read function

A NULL pointer dereference in sanei_epson_net_read in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, aka GHSL-2020-075.

sane-backends: null pointer dereference in epsonds_net_read in epsonds-net.c

A NULL pointer dereference in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, GHSL-2020-079.

sane-backends: Heap buffer overflow in esci2_img

A heap buffer overflow in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-084.

sane-backends: Reading uninitialized data in epsonds_net_read in epsonds-net.c

An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, aka GHSL-2020-081.

sane-backends: Out-of-bounds read in esci2_check_header

An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, aka GHSL-2020-083.

sane-backends: Out-of-bounds read in decode_binary

An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same local network as the victim to read important information, such as the ASLR offsets of the program, aka GHSL-2020-082.

sane-backends: Heap buffer overflow in epsonds_net_read in epsonds-net.c

A heap buffer overflow in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-080.

OpenConnect 8.09 has a buffer overflow, causing a denial of service (application crash) or possibly unspecified other impact, via crafted certificate data to get_cert_name in gnutls.c.
