CrOS: Vulnerability reported in dev-libs/openssl

Project Member Reported by vomit.go...@appspot.gserviceaccount.com, Apr 25 2018

Issue description

Automated analysis has detected that the following third party packages have had vulnerabilities publicly reported. 

NOTE: There may be several bugs listed below - in almost all cases, all bugs can be quickly addressed by upgrading to the latest version of the package.

Package Name: dev-libs/openssl
Package Version: [cpe:/a:openssl:openssl:1.0.2j cpe:/a:openssl:openssl:1.0.2k]


Advisory: CVE-2018-0739
  Details: https://vomit.googleplex.com/advisory?id=CVE/CVE-2018-0739
  CVSS severity score: 4.3/10.0
  Confidence: high
  Description:

Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).

Aditya, could you look into pulling in a newer openssl from upstream to address this? If not, would you assign it to someone who can? Thanks.
Yeah. I will take a look. I have b/78556323 assigned to me for the same.
Thanks.
