Oracle Solaris Third-Party Patch Update : gnutls (cve_2013_1619_cryptographic_issues)
Medium Nessus Plugin ID 80630
SynopsisThe remote Solaris system is missing a security patch for third-party software.
DescriptionThe remote Solaris system is missing necessary patches to address security updates :
- The TLS implementation in GnuTLS before 2.12.23, 3.0.x before 3.0.28, and 3.1.x before 3.1.7 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
- The _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in GnuTLS 2.12.23 allows remote attackers to cause a denial of service (buffer over-read and crash) via a crafted padding length. NOTE: this might be due to an incorrect fix for CVE-2013-0169.
SolutionUpgrade to Solaris 18.104.22.168.0.
