Qemu: display: cirrus: OOB read access issue

An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions for example, cirrusbitbltropfwdtransp. A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in...

CVE-2017-3731 Truncated packet could crash via OOB read

If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; user...

Internet Bug Bounty: OOB read in TS_OBJ_print_bio() (CVE-2016-2180)

The function TSOBJprintbio misuses OBJobj2txt: the return value is the total length the OID text representation would use and not the amount of data written. This will result in OOB reads when large OIDs are presented. refer: https://www.openssl.org/news/secadv/20160922.txt...

Internet Bug Bounty: Malformed SHA512 ticket DoS (CVE-2016-6302)

If a server uses SHA512 for TLS session ticket HMAC it is vulnerable to a DoS attack where a malformed ticket will result in an OOB read which will ultimately crash. The use of SHA512 in TLS session tickets is comparatively rare as it requires a custom server callback and ticket lookup mechanism...
