samba: crash in dcesrv_auth_bind_ack due to missing error check

Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not properly implement the DCE-RPC layer, which allows remote attackers to perform protocol-downgrade attacks, cause a denial of service (application crash or CPU consumption), or possibly execute arbitrary code on a client system via unspecified vectors.

Django: possible DoS by filling session store

The session backends in Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (session store consumption) via multiple requests with unique session keys.

tidy: heap buffer overflow in ParseValue()

Heap-based buffer overflow in the ParseValue function in lexer.c in tidy before 4.9.31 allows remote attackers to cause a denial of service (crash) via vectors involving a command character in an href.

tidy: heap buffer overflow in ParseValue()

The ParseValue function in lexer.c in tidy before 4.9.31 allows remote attackers to cause a denial of service (crash) via vectors involving multiple whitespace characters before an empty href, which triggers a large memory allocation.

mysql: unspecified vulnerability related to Server:DML (CPU October 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.45 and earlier and 5.6.26 and earlier allows remote authenticated users to affect availability via vectors related to Server : DML, a different vulnerability than CVE-2015-4858.

kernel: number wraparound vulnerability in function start_req()

Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

mysql: unspecified vulnerability related to Server:InnoDB (CPU October 2015)

Unspecified vulnerability in Oracle MySQL Server 5.6.25 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server : InnoDB.

python-django: Denial-of-service possibility in logout() view by filling session store

The (1) contrib.sessions.backends.base.SessionBase.flush and (2) cache_db.SessionStore.flush functions in Django 1.7.x before 1.7.10, 1.4.x before 1.4.22, and possibly other versions create empty sessions in certain circumstances, which allows remote attackers to cause a denial of service (session store consumption) via unspecified vectors.

mysql: unspecified vulnerability related to Server:DML (CPU October 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.44 and earlier, and 5.6.25 and earlier, allows remote authenticated users to affect confidentiality, integrity, and availability via vectors related to DML.

The Special:DeletedContributions page in MediaWiki before 1.23.10, 1.24.x before 1.24.3, and 1.25.x before 1.25.2 allows remote attackers to determine if an IP is autoblocked via the "Change block" text.

driver/subprocs.c in XScreenSaver before 5.34 does not properly perform an internal consistency check, which allows physically proximate attackers to bypass the lock screen by hot swapping monitors.

The decode_ihdr_chunk function in libavcodec/pngdec.c in FFmpeg before 2.7.2 does not enforce uniqueness of the IHDR (aka image header) chunk in a PNG image, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via a crafted image with two or more of these chunks.

The ff_sbr_apply function in libavcodec/aacsbr.c in FFmpeg before 2.7.2 does not check for a matching AAC frame syntax element before proceeding with Spectral Band Replication calculations, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted AAC data.

The sws_init_context function in libswscale/utils.c in FFmpeg before 2.7.2 does not initialize certain pixbuf data structures, which allows remote attackers to cause a denial of service (segmentation violation) or possibly have unspecified other impact via crafted video data.

mysql: unspecified vulnerability related to Server:Parser (CPU October 2015)

Unspecified vulnerability in Oracle MySQL Server 5.5.45 and earlier, and 5.6.26 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server : Parser.

Qemu: ide: divide by zero issue

hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.

kernel: net: rds: NULL pointer dereference in net/rds/connection.c

The __rds_conn_create function in net/rds/connection.c in the Linux kernel through 4.2.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by using a socket that was not properly bound.

rpcbind: Use-after-free vulnerability in PMAP_CALLIT

Use-after-free vulnerability in xprt_set_caller in rpcb_svc_com.c in rpcbind 0.2.1 and earlier allows remote attackers to cause a denial of service (daemon crash) via crafted packets, involving a PMAP_CALLIT code.

mysql: unspecified vulnerability related to Server:InnoDB (CPU October 2015)

Unspecified vulnerability in Oracle MySQL Server 5.6.23 and earlier allows remote authenticated users to affect availability via unknown vectors related to Server : InnoDB.
