exim: use-after-free in receive_msg function via vectors involving BDAT commands

The receive_msg function in receive.c in the SMTP daemon in Exim 4.88 and 4.89 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via vectors involving BDAT commands.

An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. Parsing the numeric header fields in a SIP message (like cseq, ttl, port, etc.) all had the potential to overflow, either causing unintended values to be captured or, if the values were subsequently converted back to strings, a buffer overrun. This will lead to a potential exploit using carefully crafted invalid values.

ImageMagick: Null pointer dereference in tiff.c

coders/tiff.c in ImageMagick before 7.0.3.7 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted image.

Qemu: 9pfs: host memory leakage via v9fs_create

The (1) v9fs_create and (2) v9fs_lcreate functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid.

Insecure use of temporary files in xbindkeys-config 0.1.3-2 allows remote attackers to execute arbitrary code.

Qemu: 9pfs: guest privilege escalation in virtfs mapped-file mode

Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest.

Cross-site scripting (XSS) vulnerability in the link dialogue in GUI editor in MoinMoin before 1.9.8 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

jasper: missing SIZ marker segment XRsiz and YRsiz fields range check

The jpc_dec_process_siz function in libjasper/jpc/jpc_dec.c in JasPer before 1.900.4 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted YRsiz value in a BMP image to the imginfo command.

jasper: missing SIZ marker segment XRsiz and YRsiz fields range check

The jpc_dec_process_siz function in libjasper/jpc/jpc_dec.c in JasPer before 1.900.4 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted XRsiz value in a BMP image to the imginfo command.

poppler: NULL pointer dereference in the FoFiTrueType::getCFFBlock function

The FoFiTrueType::getCFFBlock function in FoFiTrueType.cc in Poppler 0.59.0 has a NULL pointer dereference vulnerability due to lack of validation of a table pointer, which allows an attacker to launch a denial of service attack.

In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '#' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access control plugins for Mosquitto.

libsamplerate: Buffer overflow in calc_output_single

In libsamplerate before 0.1.9, a buffer over-read occurs in the calc_output_single function in src_sinc.c via a crafted audio file.

wireshark: NetScaler file parser infinite loop (wnpa-sec-2017-14)

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the NetScaler file parser could go into an infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by ensuring a nonzero record size.

wireshark: IMAP dissector crash (wnpa-sec-2017-12)

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the IMAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-imap.c by calculating a line's end correctly.

sox: Heap-based buffer overflow in the ImaExpandS function

There is a heap-based buffer overflow in the ImaExpandS function of ima_rw.c in Sound eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.

kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism

The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c.

Qemu: display: cirrus: OOB r/w access issues in bitblt routines

Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.

Qemu: 9pfs: host memory leakage via v9pfs_list_xattr

Memory leak in the v9fs_list_xattr function in hw/9pfs/9p-xattr.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (memory consumption) via vectors involving the orig_value variable.

Double-free vulnerability in libavformat/mov.c in FFMPEG in Google Chrome 41.0.2251.0 allows remote attackers to cause a denial of service (memory corruption and crash) via a crafted .m4a file.

sox: Reachable assertion abort in the function sox_append_comment()

There is a reachable assertion abort in the function sox_append_comment() in formats.c in Sound eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.
