CVE-2019-19580

An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations, because of an incomplete fix for CVE-2019-18421. XSA-299 addressed several critical issues in restartable PV type...

Further issues with restartable PV type change operations

ISSUE DESCRIPTION XSA-299 addressed several critical issues in restartable PV type change operations. Despite extensive testing and auditing, some corner cases were missed. IMPACT A malicious PV guest administrator may be able to escalate their privilege to that of the host. VULNERABLE SYSTEMS Al...

Kernel: page cache side channel attacks

A new software page cache side channel attack scenario was discovered in operating systems that implement the very common 'page cache' caching mechanism. A malicious user/process could use 'in memory' page-cache knowledge to infer access timings to shared memory and gain knowledge which can be us...

rack -- information leak / session hijack vulnerability

National Vulnerability Database: There's a possible information leak / session hijack vulnerability in Rack RubyGem rack. This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are...

MGASA-2019-0362 Updated libcryptopp packages fix security vulnerability

The updated packages fix a security vulnerability: Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The iss...
