Tyler Bohan of Talos discovered that FreeRDP, a free implementation of the Remote Desktop Protocol , contained several vulnerabilities that allowed a malicious remote server or a man-in-the-middle to either cause a DoS by forcibly terminating the client, or execute arbitrary code on the client side.

Several security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, use-after-frees, buffer overflows and other implementation errors may lead to the execution of arbitrary code, denial of service, bypass of the same-origin policy or incorrect enforcement of CSP.

Several vulnerabilities have been found in the PostgreSQL database system: CVE-2017-7546 In some authentication methods empty passwords were accepted. CVE-2017-7547 User mappings could leak data to unprivileged users. CVE-2017-7548 The lo_put function ignored ACLs. For more in-depth descriptions of the security vulnerabilities, please see https://www.postgresql.org/about/news/1772/

Guido Vranken discovered that FreeRADIUS, an open source implementation of RADIUS, the IETF protocol for AAA , did not properly handle memory when processing packets. This would allow a remote attacker to cause a denial-of-service by application crash, or potentially execute arbitrary code. All those issues are covered by this single DSA, but it"s worth noting that not all issues affect all releas ...

It was discovered that CVS, a centralised version control system, did not correctly handle maliciously constructed repository URLs, which allowed an attacker to run an arbitrary shell command.

Aleksandar Nikolic of Cisco Talos discovered a stack-based buffer overflow vulnerability in libsoup2.4, a HTTP library implementation in C. A remote attacker can take advantage of this flaw by sending a specially crafted HTTP request to cause an application using the libsoup2.4 library to crash , or potentially execute arbitrary code.

Several problems were discovered in Subversion, a centralised version control system. CVE-2017-9800 Joern Schneeweisz discovered that Subversion did not correctly handle maliciously constructed svn+ssh:// URLs. This allowed an attacker to run an arbitrary shell command, for instance via svn:externals properties or when using "svnsync sync".

It was discovered that libsmpack, a library used to handle Microsoft compression formats, did not properly validate its input. A remote attacker could craft malicious CAB or CHM files and use this flaw to cause a denial of service via application crash, or potentially execute arbitrary code.

Han Han of Red Hat discovered that augeas, a configuration editing tool, improperly handled some escaped strings. A remote attacker could leverage this flaw by sending maliciously crafted strings, thus causing an augeas-enabled application to crash or potentially execute arbitrary code.

Hossein Lotfi and Jakub Jirasek from Secunia Research have discovered multiple vulnerabilities in LibRaw, a library for reading RAW images. An attacker could cause a memory corruption leading to a DoS with craft KDC or TIFF file.
