In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash.Show less

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.Show less

The FoFiType1C::convertToType0 function in FoFiType1C.cc in Poppler 0.59.0 has a heap-based buffer over-read vulnerability if an out-of-bounds font dictionary index is encountered, which allows an attacker to launch a denial of service attack.Show less

The FoFiType1C::convertToType0 function in FoFiType1C.cc in Poppler 0.59.0 has a NULL pointer dereference vulnerability because a data structure is not initialized, which allows an attacker to launch a denial of service attack.Show less

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.Show less

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.Show less

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.Show less

A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash.Show less

The bark_noise_hybridmp function in psy.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact via a crafted mp4 file.Show less
