libvncserver: NULL pointer dereference flaw in framebuffer setup

The HandleRFBServerMessage function in libvncclient/rfbproto.c in LibVNCServer 0.9.9 and earlier does not check certain malloc return values, which allows remote VNC servers to cause a denial of service (application crash) or possibly execute arbitrary code by specifying a large screen size in a (1) FramebufferUpdate, (2) ResizeFrameBuffer, or (3) PalmVNCReSizeFrameBuffer message.

libevent: potential heap overflow in buffer/bufferevent APIs

Multiple integer overflows in the evbuffer API in Libevent 1.4.x before 1.4.15, 2.0.x before 2.0.22, and 2.1.x before 2.1.5-beta allow context-dependent attackers to cause a denial of service or possibly have other unspecified impact via "insanely large inputs" to the (1) evbuffer_add, (2) evbuffer_expand, or (3) bufferevent_write function, which triggers a heap-based buffer overflow or an infinite loop. NOTE: this identifier has been SPLIT per ADT3 due to different affected versions. See CVE-2015-6525 for the functions that are only affected in 2.0 and later.

Buffer overflow in the HTTP transport code in apt-get in APT 1.0.1 and earlier allows man-in-the-middle attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted URL.

schema.py in Roundup before 1.5.1 does not properly limit attributes included in default user permissions, which might allow remote authenticated users to obtain sensitive user information by viewing user details.

Drupal 6.x before 6.34 and 7.x before 7.34 allows remote attackers to hijack sessions via a crafted request, as demonstrated by a crafted request to a server that supports both HTTP and HTTPS sessions.

The password hashing API in Drupal 7.x before 7.34 and the Secure Password Hashes (aka phpass) module 6.x-2.x before 6.x-2.1 for Drupal allows remote attackers to cause a denial of service (CPU and memory consumption) via a crafted request.

SQL injection vulnerability in the XML-RPC interface in Movable Type before 5.18, 5.2.x before 5.2.11, and 6.x before 6.0.6 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

graphviz: format string vulnerability in yyerror()

Format string vulnerability in the yyerror function in lib/cgraph/scan.l in Graphviz allows remote attackers to have unspecified impact via format string specifiers in unknown vectors, which are not properly handled in an error string.

Cross-site scripting (XSS) vulnerability in file_download.php in MantisBT before 1.2.18 allows remote authenticated users to inject arbitrary web script or HTML via a Flash file with an image extension, related to inline attachments, as demonstrated by a .swf.jpeg filename.

The string_insert_href function in MantisBT 1.2.0a1 through 1.2.x before 1.2.18 does not properly validate the URL protocol, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the javascript:// protocol.

hivex: missing checks for small-sized files

lib/handle.c in Hivex before 1.3.11 allows local users to execute arbitrary code and gain privileges via a small hive files, which triggers an out-of-bounds read or write.

UnRTF allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code as demonstrated by a file containing the string "{\cb-999999999".

kernel: crypto api unprivileged arbitrary module load via request_module()

The Crypto API in the Linux kernel before 3.18.5 allows local users to load arbitrary kernel modules via a bind system call for an AF_ALG socket with a parenthesized module template expression in the salg_name field, as demonstrated by the vfat(aes) expression, a different vulnerability than CVE-2013-7421.

freetype: out-of-bounds read in tt_cmap4_validate()

The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field's value is completely calculated, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table.

freetype: off-by-one buffer over-read in parse_charstrings() / t42_parse_charstrings()

FreeType before 2.5.4 does not check for the end of the data during certain parsing actions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted Type42 font, related to type42/t42parse.c and type1/t1load.c.

freetype: integer overflow in tt_sbit_decoder_init() leading to out-of-bounds read

The tt_sbit_decoder_init function in sfnt/ttsbit.c in FreeType before 2.5.4 proceeds with a count-to-size association without restricting the count value, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted embedded bitmap.

freetype: integer overflow in tt_face_load_font_dir() leading to out-of-bounds read

sfnt/ttload.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting the values, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted SFNT table.

The default slapd configuration in the Debian openldap package 2.4.23-3 through 2.4.39-1.1 allows remote authenticated users to modify the user's permissions and other user attributes via unspecified vectors.

Qemu: PRDT overflow from guest to host

The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU 1.0 through 2.1.3 have multiple interpretations of a function's return value, which allows guest OS users to cause a host OS denial of service (memory consumption or infinite loop, and system crash) via a PRDT with zero complete sectors, related to the bmdma_prepare_buf and ahci_dma_prepare_buf functions.

imlib2 before 1.4.7 allows remote attackers to cause a denial of service (segmentation fault) via a GIF image without a colormap.
