CVE-2019-18197 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2020-08-24 5.1 MEDIUM 7.5 HIGH
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
CVE-2018-14551 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2020-08-24 7.5 HIGH 9.8 CRITICAL
The ReadMATImageV4 function in coders/mat.c in ImageMagick 7.0.8-7 uses an uninitialized variable, leading to memory corruption.
CVE-2018-18397 3 Canonical, Linux, Redhat 10 Ubuntu Linux, Linux Kernel, Enterprise Linux Desktop and 7 more 2020-08-24 2.1 LOW 5.5 MEDIUM
The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.
CVE-2019-6212 3 Apple, Canonical, Microsoft 7 Icloud, Iphone Os, Itunes and 4 more 2020-08-24 6.8 MEDIUM 8.8 HIGH
Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2019-7663 4 Canonical, Debian, Libtiff and 1 more 4 Ubuntu Linux, Debian Linux, Libtiff and 1 more 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
An Invalid Address dereference was discovered in TIFFWriteDirectoryTagTransferfunction in libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the cpSeparateBufToContigBuf function in tiffcp.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted tiff file. This is different from CVE-2018-12900.
CVE-2018-5160 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 5.0 MEDIUM 7.5 HIGH
WebRTC can use a "WrappedI420Buffer" pixel buffer but the owning image object can be freed while it is still in use. This can result in the WebRTC encoder using uninitialized memory, leading to a potentially exploitable crash. This vulnerability affects Firefox < 60.
CVE-2018-12403 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 5.0 MEDIUM 5.3 MEDIUM
If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. This vulnerability affects Firefox < 63.
CVE-2018-0500 2 Canonical, Haxx 2 Ubuntu Linux, Curl 2020-08-24 7.5 HIGH 9.8 CRITICAL
Curl_smtp_escape_eob in lib/smtp.c in curl 7.54.1 to and including curl 7.60.0 has a heap-based buffer overflow that might be exploitable by an attacker who can control the data that curl transmits over SMTP with certain settings (i.e., use of a nonstandard --limit-rate argument or CURLOPT_BUFFERSIZE value).
CVE-2018-6797 4 Canonical, Debian, Perl and 1 more 5 Ubuntu Linux, Debian Linux, Perl and 2 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.
CVE-2018-5168 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2020-08-24 5.0 MEDIUM 5.3 MEDIUM
Sites can bypass security checks on permissions to install lightweight themes by manipulating the "baseURI" property of the theme element. This could allow a malicious site to install a theme without user interaction which could contain offensive or embarrassing images. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2019-3824 3 Canonical, Debian, Samba 3 Ubuntu Linux, Debian Linux, Samba 2020-08-24 4.0 MEDIUM 6.5 MEDIUM
A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service.
CVE-2019-15030 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2020-08-24 3.6 LOW 4.4 MEDIUM
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via a Facility Unavailable exception. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process because of a missing arch/powerpc/kernel/process.c check.
CVE-2018-11683 3 Canonical, Liblouis, Opensuse 3 Ubuntu Linux, Liblouis, Leap 2020-08-24 6.8 MEDIUM 8.8 HIGH
Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c, a different vulnerability than CVE-2018-11440.
CVE-2018-15471 3 Canonical, Linux, Xen 3 Ubuntu Linux, Linux Kernel, Xen 2020-08-24 6.8 MEDIUM 7.8 HIGH
An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks.
CVE-2019-8907 4 Canonical, Debian, File Project and 1 more 4 Ubuntu Linux, Debian Linux, File and 1 more 2020-08-24 6.8 MEDIUM 8.8 HIGH
do_core_note in readelf.c in libmagic.a in file 5.35 allows remote attackers to cause a denial of service (stack corruption and application crash) or possibly have unspecified other impact.
CVE-2018-12015 6 Apple, Archive\, Canonical and 3 more 9 Mac Os X, \, Ubuntu Linux and 6 more 2020-08-24 6.4 MEDIUM 7.5 HIGH
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.
CVE-2018-7566 6 Canonical, Debian, Linux and 3 more 12 Ubuntu Linux, Debian Linux, Linux Kernel and 9 more 2020-08-24 4.6 MEDIUM 7.8 HIGH
The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user.
CVE-2019-6215 3 Apple, Canonical, Microsoft 8 Icloud, Iphone Os, Itunes and 5 more 2020-08-24 6.8 MEDIUM 8.8 HIGH
A type confusion issue was addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.
CVE-2018-18497 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects Firefox < 64.
CVE-2018-6913 3 Canonical, Debian, Perl 3 Ubuntu Linux, Debian Linux, Perl 2020-08-24 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.
