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: 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: 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: 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.

qemu: OOB read and write due to integer overflow in sm501_2d_operation() in hw/display/sm501.c

In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service.

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.

exim: out-of-bounds read in the SPA authenticator can lead to SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c

Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c.

kernel: deadlock if a coalescing operation fails in btree_gc_coalesce function in drivers/md/bcache/btree.c

An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails.

kernel: sg_write function lacks an sg_remove_request call in a certain failure case

An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.

kernel: memory leak in svm_cpu_init function in arch/x86/kvm/svm.c

An issue was discovered in the Linux kernel before 5.6. svm_cpu_uninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will

libexif: divide-by-zero in exif_entry_get_value function in exif-entry.c

exif_entry_get_value in exif-entry.c in libexif 0.6.21 has a divide-by-zero error.

hostapd: UPnP SUBSCRIBE misbehavior in WPS AP

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.

Slurm 19.05.x before 19.05.7 and 20.02.x before 20.02.3, in the rare case where Message Aggregation is enabled, allows Authentication Bypass via an Alternate Path or Channel. A race condition allows a user to launch a process as an arbitrary user.

dovecot: Crash due to assert in RPA implementation

In Dovecot before 2.3.11.3, sending a specially formatted RPA request will crash the auth service because a length of zero is mishandled.

dovecot: Out of bound reads in dovecot NTLM implementation

In Dovecot before 2.3.11.3, sending a specially formatted NTLM request will crash the auth service because of an out-of-bounds read.

GraphicsMagick through 1.3.35 has a heap-based buffer overflow in ReadMNGImage in coders/png.c.
