Buffer overflow

Buffer overflows were discovered in Contiki-NG 4.4 through 4.5, in the SNMP agent. Functions parsing the OIDs in SNMP requests lack sufficient allocated target-buffer capacity verification when writing parsed OID values. The function snmpoiddecodeoid may overwrite memory areas beyond the provided...

CVE-2020-14936

CVE-2020-14936 concerns Contiki-NG 4.4–4.5, where the SNMP agent contains a buffer overflow in snmp_oid_decode_oid() triggered during SNMP request processing. The function does not sufficiently validate target-buffer capacity when writing parsed OID values, risking overwriting memory beyond the i...

CVE-2020-8904

An arbitrary memory overwrite vulnerability in the trusted memory of Asylo exists in versions prior to 0.6.0. As the ecallrestore function fails to validate the range of the outputlen pointer, an attacker can manipulate the tmpoutputlen value and write to an arbitrary location in the trusted...

CVE-2020-8904 Arbitrary trusted memory overwrite vulnerability in Asylo

An arbitrary memory overwrite vulnerability in the trusted memory of Asylo exists in versions prior to 0.6.0. As the ecallrestore function fails to validate the range of the outputlen pointer, an attacker can manipulate the tmpoutputlen value and write to an arbitrary location in the trusted...

CVE-2020-8904

The CVE-2020-8904 entry concerns Asylo prior to 0.6.0, where the ecall_restore function does not validate the range of the output_len pointer, allowing an attacker to manipulate tmp_output_len and overwrite arbitrary trusted (enclave) memory. Affected product: Asylo (pre-0.6.0). Impact described:...

Important: kernel

Issue Overview: An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in drivers/gpu/drm/i915/i915gemexecbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory...

CVE-2020-0235

In crusspsharedioctl we first copy 4 bytes from userdata into "size" variable, and then use that variable as the size parameter for "copyfromuser", ending up overwriting memory following "crussphdr". "crussphdr" is a static variable, of type "struct crusspioctlheader".Product: AndroidVersions:...
