[Security Fix]
- TLS プロトコルには暗号化されていないデータの長さを適切に不明瞭にせずに圧縮されたデータを暗号化し，"CRIME" 攻撃によって，中間者攻撃を行う攻撃者が平文の HTTP ヘッダを取得する脆弱性があります。(CVE-2012-4929)
- OpenSSL が OCSP レスポンスのための署名の検証を適切に行なっておらず，不正なキーによって，リ
モートの攻撃者がサービス拒否 (ヌルポインタ逆参照とアプリケーションのクラッシュ) を引き起こす脆弱性があります。 (CVE-2013-0166)
- OpenSSL, OpenJDK, PolarSSL や他の製品で使用されている TLS プロトコル，DTLS プロトコルは不正な CBC パディングの処理の間，MAC チェック要求でのタイミングサイドチャネル攻撃を適切に考慮しておらず，巧妙に細工されたパケットのタイミングデータの統計的分析によって，リモートの攻撃者が distinguishing 攻撃と平文回復攻撃 (plaintext-recovery attack) を行う脆弱性があります。(CVE-2013-0169)

CVE:
CVE-2013-0169
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do 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-2013-0166
OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key.

CVE-2012-4929
The TLS protocol 1.2 and earlier, as used in Mozilla Firefox, Google Chrome, Qt, and other products, can encrypt compressed data without properly obfuscating the length of the unencrypted data, which allows man-in-the-middle attackers to obtain plaintext HTTP headers by observing length differences during a series of guesses in which a string in an HTTP request potentially matches an unknown string in an HTTP header, aka a "CRIME" attack.
