In ImageMagick 7.0.7-37 Q16, SetGrayscaleImage in the quantize.c file allows attackers to cause a heap-based buffer over-read via a crafted file.
CVE-2018-11577 3 Canonical, Liblouis, Opensuse 3 Ubuntu Linux, Liblouis, Leap 2019-10-02 6.8 MEDIUM 8.8 HIGH
Liblouis 3.5.0 has a Segmentation fault in lou_logPrint in logging.c.
CVE-2018-1122 3 Canonical, Debian, Procps-ng Project 3 Ubuntu Linux, Debian Linux, Procps-ng 2019-10-02 4.4 MEDIUM 7.0 HIGH
procps-ng before version 3.3.15 is vulnerable to a local privilege escalation in top. If a user runs top with HOME unset in an attacker-controlled directory, the attacker could achieve privilege escalation by exploiting one of several vulnerabilities in the config_file() function.
CVE-2018-11214 3 Canonical, Debian, Ijg 3 Ubuntu Linux, Debian Linux, Libjpeg 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in libjpeg 9a. The get_text_rgb_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file.
CVE-2018-11213 3 Canonical, Debian, Ijg 3 Ubuntu Linux, Debian Linux, Libjpeg 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in libjpeg 9a. The get_text_gray_row function in rdppm.c allows remote attackers to cause a denial of service (Segmentation fault) via a crafted file.
CVE-2018-10999 3 Canonical, Debian, Exiv2 3 Ubuntu Linux, Debian Linux, Exiv2 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in Exiv2 0.26. The Exiv2::Internal::PngChunk::parseTXTChunk function has a heap-based buffer over-read.
CVE-2018-10963 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF through 4.0.9 allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file, a different vulnerability than CVE-2017-13726.
CVE-2018-10938 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-02 7.1 HIGH 5.9 MEDIUM
A flaw was found in the Linux kernel present since v4.0-rc1 and through v4.13-rc4. A crafted network packet sent remotely by an attacker may force the kernel to enter an infinite loop in the cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a denial-of-service. A certain non-default configuration of LSM (Linux Security Module) and NetLabel should be set up on a system before an attacker could leverage this flaw.
CVE-2018-10853 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-02 4.6 MEDIUM 7.8 HIGH
A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.
CVE-2018-10805 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
ImageMagick version 7.0.7-28 contains a memory leak in ReadYCBCRImage in coders/ycbcr.c.
CVE-2018-10804 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
ImageMagick version 7.0.7-28 contains a memory leak in WriteTIFFImage in coders/tiff.c.
CVE-2018-10779 2 Canonical, Libtiff 2 Ubuntu Linux, Libtiff 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a heap-based buffer over-read, as demonstrated by bmp2tiff.
CVE-2018-1061 5 Canonical, Debian, Fedoraproject and 2 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in the difflib.IS_LINE_JUNK method. An attacker could use this flaw to cause denial of service.
CVE-2018-10546 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. An infinite loop exists in ext/iconv/iconv.c because the iconv stream filter does not reject invalid multibyte sequences.
CVE-2018-1000301 5 Canonical, Debian, Haxx and 2 more 9 Ubuntu Linux, Debian Linux, Curl and 6 more 2019-10-02 6.4 MEDIUM 9.1 CRITICAL
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content.. This vulnerability appears to have been fixed in curl < 7.20.0 and curl >= 7.60.0.
CVE-2018-1000204 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2019-10-02 6.3 MEDIUM 5.3 MEDIUM
** DISPUTED ** Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it "virtually impossible to exploit."
CVE-2018-1000122 5 Canonical, Debian, Haxx and 2 more 9 Ubuntu Linux, Debian Linux, Curl and 6 more 2019-10-02 6.4 MEDIUM 9.1 CRITICAL
A buffer over-read exists in curl 7.20.0 to and including curl 7.58.0 in the RTSP+RTP handling code that allows an attacker to cause a denial of service or information leakage
CVE-2018-1000024 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2019-10-02 5.0 MEDIUM 7.5 HIGH
The Squid Software Foundation Squid HTTP Caching Proxy version 3.0 to 3.5.27, 4.0 to 4.0.22 contains a Incorrect Pointer Handling vulnerability in ESI Response Processing that can result in Denial of Service for all clients using the proxy.. This attack appear to be exploitable via Remote server delivers an HTTP response payload containing valid but unusual ESI syntax.. This vulnerability appears to have been fixed in 4.0.23 and later.
