EmbedThis GoAhead 3.0.0 through 3.4.1 does not properly handle path segments starting with a . (dot), which allows remote attackers to conduct directory traversal attacks, cause a denial of service (heap-based buffer overflow and crash), or possibly execute arbitrary code via a crafted URI.

Embedthis Appweb before 4.6.6 and 5.x before 5.2.1 allows remote attackers to cause a denial of service (NULL pointer dereference) via a Range header with an empty value, as demonstrated by "Range: x=,".

gd: buffer read overflow in gd_gif_in.c

The GetCode_ function in gd_gif_in.c in GD 2.1.1 and earlier, as used in PHP before 5.5.21 and 5.6.x before 5.6.5, allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted GIF image that is improperly handled by the gdImageCreateFromGif function.

Kernel: fs: btrfs: non-atomic xattr replace operation

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.

Multiple cross-site scripting (XSS) vulnerabilities in the Investigative Reports in Websense TRITON AP-WEB before 8.0.0 and Web Security and Filter, Web Security Gateway, and Web Security Gateway Anywhere 7.8.3 before Hotfix 02 and 7.8.4 before Hotfix 01 allow remote attackers to inject arbitrary web script or HTML via the (1) ReportName (Job Name) parameter to the Explorer report scheduler (cgi-bin/WsCgiExplorerSchedule.exe) in the Job Queue or the col parameter to the (2) Names or (3) Anonymous (explorer_wse/explorer_anon.exe) summary report page.

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.

Cross-site scripting (XSS) vulnerability in the WddxPacket::recursiveAddVar function in HHVM (aka the HipHop Virtual Machine) before 3.5.0 allows remote attackers to inject arbitrary web script or HTML via a crafted string to the wddx_serialize_value function.

kernel: netfilter connection tracking extensions denial of service

include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment.

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.

zeromq: protocol downgrade attack on sockets using the ZMTP v3 protocol

libzmq before 4.0.6 and 4.1.x before 4.1.1 allows remote attackers to conduct downgrade attacks and bypass ZMTP v3 protocol security mechanisms via a ZMTP v2 or earlier header.

Kernel: fs: udf: heap overflow in __udf_adinicb_readpage

The udf_pc_to_char function in fs/udf/symlink.c in the Linux kernel before 3.18.2 relies on component lengths that are unused, which allows local users to cause a denial of service (system crash) via a crafted UDF filesystem image.

Directory traversal vulnerability in the Slider Revolution (revslider) plugin before 4.2 for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the img parameter in a revslider_show_image action to wp-admin/admin-ajax.php.

freetype: heap-based buffer overflow in cff/cf2ft.c

cff/cf2ft.c in FreeType before 2.5.4 does not validate the return values of point-allocation functions, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted OTF font.

freetype: out of bounds read in Type42 font parser

type42/t42parse.c in FreeType before 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font.

freetype: missing ENDCHAR NULL pointer dereference in the _bdf_parse_glyphs()

The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font.

freetype: stack-based buffer overflow in cff/cf2intrp.c in the CFF CharString interpreter

cff/cf2intrp.c in the CFF CharString interpreter in FreeType before 2.5.4 proceeds with additional hints after the hint mask has been computed, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow) via a crafted OpenType font. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-2240.

Qemu: scsi: esp: OOB r/w access while processing ESP_FIFO

The (1) esp_reg_read and (2) esp_reg_write functions in hw/scsi/esp.c in QEMU allow local guest OS administrators to cause a denial of service (QEMU process crash) or execute arbitrary code on the QEMU host via vectors related to the information transfer buffer.

freetype: buffer over-read and integer underflow in tt_face_load_kern()

The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4 enforces an incorrect minimum table length, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.

freetype: off-by-one buffer over-read in tt_face_load_hdmx()

The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.

freetype: integer underflow in the tt_sbit_decoder_load_image()

The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 does not properly check for an integer overflow, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType font.
