MGASA-2013-0290 - Updated polarssl package fixes security vulnerabilities
Publication date: 24 Sep 2013
URL: http://advisories.mageia.org/MGASA-2013-0290.html
Type: security
Affected Mageia releases: 3
CVE: CVE-2013-0169,
CVE-2013-1621,
CVE-2013-4623
Description:
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used
in PolarSSL before 1.2.6, does not properly consider timing side-channel
attacks on a MAC check requirement 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, aka the "Lucky Thirteen" issue (CVE-2013-0169).
Array index error in the SSL module in PolarSSL before 1.2.6 might allow
remote attackers to cause a denial of service via vectors involving a
crafted padding-length value during validation of CBC padding in a TLS
session (CVE-2013-1621).
A third party can set up a SSL/TLS handshake with a server and send a
malformed Certificate handshake message that results in an infinite loop
for that connection. With a Man-in-the-Middle attack on a client, a third
party can trigger the same infinite loop on a client (CVE-2013-4623).
