Index Functions Privilege Escalation : as a unique feature, PostgreSQL allows users to create indexes on the results of user-defined functions, known as expression indexes. This provided two vulnerabilities to privilege escalation: index functions were executed as the superuser and not the table owner during VACUUM and ANALYZE, and that SET ROLE and SET SESSION AUTHORIZATION were permitted withi ...

A vulnerability has been found and corrected in expat: The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE ...

Multiple vulnerabilities was discovered and corrected in python: Buffer underflow in the rgbimg module in Python 2.5 allows remote attackers to cause a denial of service via a large ZSIZE value in a black-and-white RGB image that triggers an invalid pointer dereference . Integer overflow in rgbimgmodule.c in the rgbimg module in Python 2.5 allows remote attackers to have an unspecified impact vi ...

Multiple vulnerabilities was discovered and corrected in python: The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that term ...

Multiple vulnerabilities has been found and corrected in python: Multiple integer overflows in audioop.c in the audioop module in Ptthon allow context-dependent attackers to cause a denial of service via a large fragment, as demonstrated by a call to audioop.lin2lin with a long string in the first argument, leading to a buffer overflow. NOTE: this vulnerability exists because of an incorrect fix ...

Multiple Java OpenJDK security vulnerabilities has been identified and fixed: The design of the W3C XML Signature Syntax and Processing recommendation specifies an HMAC truncation length but does not require a minimum for its length, which allows attackers to spoof HMAC-based signatures and bypass authentication by specifying a truncation length with a small number of bits . The Java Web Start f ...

A vulnerability was discovered and corrected in the Linux 2.6 kernel: The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an ...
