dnsmasq: stack buffer overflow in the DHCPv6 code

Stack-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DHCPv6 request.

dnsmasq: information leak in the DHCPv6 relay code

dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests.

dnsmasq: memory exhaustion vulnerability in the EDNS0 code

Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation.

dnsmasq: integer underflow leading to buffer over-read in the EDNS0 code

Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request.

kernel: buffer overflow in tpacket_rcv() in net/packet/af_packet.c

The tpacket_rcv function in net/packet/af_packet.c in the Linux kernel before 4.13 mishandles vnet headers, which might allow local users to cause a denial of service (buffer overflow, and disk and memory corruption) or possibly have unspecified other impact via crafted system calls.

ReadPNMImage in coders/pnm.c in GraphicsMagick 1.3.26 does not ensure the correct number of colors for the XV 332 format, leading to a NULL Pointer Dereference.

ImageMagick: Use-after-free in the TIFFSetProfiles function

The TIFFSetProfiles function in coders/tiff.c in ImageMagick 7.0.6 has incorrect expectations about whether LibTIFF TIFFGetField return values imply that data validation has occurred, which allows remote attackers to cause a denial of service (use-after-free after an invalid call to TIFFSetField, and application crash) via a crafted file.

nautilus: Insufficient validation of trust of .desktop files with execute permission

GNOME Nautilus before 3.23.90 allows attackers to spoof a file type by using the .desktop file extension, as demonstrated by an attack in which a .desktop file's Name field ends in .pdf but this file's Exec field launches a malicious "sh -c" command. In other words, Nautilus provides no UI indication that a file actually has the potentially unsafe .desktop extension; instead, the UI only shows the .pdf extension. One (slightly) mitigating factor is that an attack requires the .desktop file to have execute permission. The solution is to ask the user to confirm that the file is supposed to be treated as a .desktop file, and then remember the user's answer in the metadata::trusted field.

ImageMagick: Out-of-bounds read in ReadTIFFImage in coders/tiff.c

In ImageMagick 7.0.7-4 Q16, an out of bounds read flaw related to ReadTIFFImage has been reported in coders/tiff.c. An attacker could possibly exploit this flaw to disclose potentially sensitive memory or cause an application crash.

libvorbis: Invalid freeing of uninitialized memory in the function vorbis_analysis_headerout()

Xiph.Org libvorbis 1.3.5 allows Remote Code Execution upon freeing uninitialized memory in the function vorbis_analysis_headerout() in info.c when vi->channels<=0, a similar issue to Mozilla bug 550184.

libvorbis: Out-of-bounds array read in the function mapping0_forward()

In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the function mapping0_forward() in mapping0.c, which may lead to DoS when operating on a crafted audio file with vorbis_analysis().

libsndfile: Divide-by-zero in the double64_init() function

In libsndfile 1.0.28, a divide-by-zero error exists in the function double64_init() in double64.c, which may lead to DoS when playing a crafted audio file.

ReadRLEImage in coders/rle.c in GraphicsMagick 1.3.26 mishandles RLE headers that specify too few colors, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file.

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.

samba: Use-after-free in processing SMB1 requests

Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request.

exiv2: Invalid memory address dereference in Exiv2::StringValueBase::read

An Invalid memory address dereference was discovered in Exiv2::StringValueBase::read in value.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.

exiv2: Invalid memory address dereference in the Exiv2::DataValue::read

An Invalid memory address dereference was discovered in Exiv2::DataValue::read in value.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.

exiv2: Invalid memory address dereference in Exiv2::getULong

An Invalid memory address dereference was discovered in Exiv2::getULong in types.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.

git: cvsserver command injection

Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before 2.12.5, 2.13.x before 2.13.6, and 2.14.x before 2.14.2 uses unsafe Perl scripts to support subcommands such as cvsserver, which allows attackers to execute arbitrary OS commands via shell metacharacters in a module name. The vulnerable code is reachable via git-shell even without CVS support.

poppler: NULL pointer dereference in the AnnotRichMedia::Content::Content

In Poppler 0.59.0, a NULL Pointer Dereference exists in AnnotRichMedia::Content::Content in Annot.cc via a crafted PDF document.
