ImageMagick: Memory exhaustion in ReadBMPImage function in coders/bmp.c in ImageMagick

The ReadBMPImage function in coders/bmp.c in ImageMagick 7.0.6-6 allows remote attackers to cause a denial of service (memory consumption) via a crafted BMP file.

ImageMagick: Use-after-free vulnerability in the DestroyImage function

Use-after-free vulnerability in the DestroyImage function in image.c in ImageMagick before 7.0.6-6 allows remote attackers to cause a denial of service via a crafted file.

Solr: Code execution via entity expansion

Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.

ImageMagick: Memory exhaustion in ReadOneLayer function in coders/xcf.c

The ReadOneLayer function in coders/xcf.c in ImageMagick 7.0.6-6 allows remote attackers to cause a denial of service (memory consumption) via a crafted file.

ImageMagick: Memory exhaustion in ReadVIFFImage function in coders/viff.c

The ReadVIFFImage function in coders/viff.c in ImageMagick 7.0.6-6 allows remote attackers to cause a denial of service (memory consumption) via a crafted VIFF file.

wpa_supplicant: Reinstallation of the pairwise key in the 4-way handshake

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.

dnsmasq: Size parameter overflow via large DNS query

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.

ImageMagick: NULL pointer dereference in the TIFFIgnoreTags function

ImageMagick 7.0.7-0 has a NULL Pointer Dereference in TIFFIgnoreTags in coders/tiff.c.

php: Out-of-bound read in timelib_meridian()

In PHP before 5.6.32, 7.x before 7.0.25, and 7.1.x before 7.1.11, an error in the date extension's timelib_meridian handling of 'front of' and 'back of' directives could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this is a different issue than CVE-2017-11145.

nasm: Use-after-free in the detoken() function

In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool nasm. The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.

ubuntu-image 1.0 before 2017-07-07, when invoked as non-root, creates files in the resulting image with the uid of the invoking user. When the resulting image is booted, a local attacker with the same uid as the image creator has unintended access to cloud-init and snapd directories.

nasm: Heap buffer overflow in the preproc.c

In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.

jasper: NULL pointer exception in jp2_encode()

JasPer 2.0.12 is vulnerable to a NULL pointer exception in the function jp2_encode which failed to check to see if the image contained at least one component resulting in a denial-of-service.

Kernel: KVM: DoS via write flood to I/O port 0x80

The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic.

ImageMagick: Improper EOF handling in coders/rle.c can trigger crash (Incomplete fix for CVE-2017-9144)

In ImageMagick before 7.0.5-10, a crafted RLE image can trigger a crash because of incorrect EOF handling in coders/rle.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-9144.

rubygems: Arbitrary file overwrite due to incorrect validation of specification name

RubyGems version 2.6.12 and earlier fails to validate specification names, allowing a maliciously crafted gem to potentially overwrite any file on the filesystem.

rubygems: DNS hijacking vulnerability

RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls.

exim: Possible information disclosure to remote atacker

Exim before 4.87.1 might allow remote attackers to obtain the private DKIM signing key via vectors related to log files and bounce messages.

rubygems: Unsafe object deserialization through YAML formatted gem specifications

RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability. YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution.

kernel: Buffer overflow in mp_override_legacy_irq()

Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel through 3.2 allows local users to gain privileges via a crafted ACPI table.
