server/telecom/CallsManager.java in Telephony in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 does not properly consider whether a device is provisioned, which allows physically proximate attackers to bypass the Factory Reset Protection protection mechanism and delete data via unspecified vectors, aka internal bug 26303187.

mail/compose/ComposeActivity.java in AOSP Mail in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 supports file:///data attachments, which allows attackers to obtain sensitive information via a crafted application, aka internal bugs 7154234 and 26989185.

rootdir/init.rc in Android 4.x before 4.4.4 does not ensure that the /data/tombstones directory exists for the Debuggerd component, which allows attackers to gain privileges via a crafted application, aka internal bug 26403620.

server/content/SyncStorageEngine.java in SyncStorageEngine in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 mismanages certain authority data, which allows attackers to cause a denial of service (reboot loop) via a crafted application, aka internal bug 26513719.

libs/gui/BufferQueueConsumer.cpp in mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 does not check for the android.permission.DUMP permission, which allows attackers to obtain sensitive information, and consequently bypass an unspecified protection mechanism, via a dump request, as demonstrated by obtaining Signature or SignatureOrSystem access, aka internal bug 27046057.

MPEG4Extractor.cpp in libstagefright in mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read and memory corruption) via a crafted media file, aka internal bug 27208621.

Sonivox in mediaserver in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 does not check for a negative number of samples, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted media file, related to arm-wt-22k/lib_src/eas_wtengine.c and arm-wt-22k/lib_src/eas_wtsynth.c, aka internal bug 26366256.

The caching functionality in the TrustManagerImpl class in TrustManagerImpl.java in Conscrypt in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49H, and 6.x before 2016-03-01 mishandles the distinction between an intermediate CA and a trusted root CA, which allows man-in-the-middle attackers to spoof servers by leveraging access to an intermediate CA to issue a certificate, aka internal bug 26232830.

The MPEG4Source::fragmentedRead function in MPEG4Extractor.cpp in libstagefright in mediaserver in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49H, and 6.x before 2016-03-01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted media file, aka internal bug 26365349.

Multiple integer overflows in libeffects in mediaserver in Android 4.x before 4.4.4, 5.x before 5.1.1 LMY49H, and 6.x before 2016-03-01 allow attackers to gain privileges via a crafted application, as demonstrated by obtaining Signature or SignatureOrSystem access, related to EffectBundle.cpp and EffectReverb.cpp, aka internal bug 26347509.
