CVE-2018-18849 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2024-11-21 2.1 LOW 5.5 MEDIUM
In Qemu 3.0.0, lsi_do_msgin in hw/scsi/lsi53c895a.c allows out-of-bounds access by triggering an invalid msg_len value.
CVE-2018-18751 3 Canonical, Gnu, Redhat 3 Ubuntu Linux, Gettext, Enterprise Linux 2024-11-21 7.5 HIGH 9.8 CRITICAL
An issue was discovered in GNU gettext 0.19.8. There is a double free in default_add_message in read-catalog.c, related to an invalid free in po_gram_parse in po-gram-gen.y, as demonstrated by lt-msgfmt.
CVE-2018-18710 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.
CVE-2018-18690 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 4.9 MEDIUM 5.5 MEDIUM
In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.
CVE-2018-18661 2 Canonical, Libtiff 2 Ubuntu Linux, Libtiff 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in LibTIFF 4.0.9. There is a NULL pointer dereference in the function LZWDecode in the file tif_lzw.c.
CVE-2018-18653 1 Canonical 1 Ubuntu Linux 2024-11-21 7.2 HIGH 7.8 HIGH
The Linux kernel, as used in Ubuntu 18.10 and when booted with UEFI Secure Boot enabled, allows privileged local users to bypass intended Secure Boot restrictions and execute untrusted code by loading arbitrary kernel modules. This occurs because a modified kernel/module.c, in conjunction with certain configuration options, leads to mishandling of the result of signature verification.
CVE-2018-18585 6 Canonical, Debian, Kyzer and 3 more 8 Ubuntu Linux, Debian Linux, Libmspack and 5 more 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
chmd_read_headers in mspack/chmd.c in libmspack before 0.8alpha accepts a filename that has '\0' as its first or second character (such as the "/\0" name).
CVE-2018-18584 7 Cabextract Project, Canonical, Debian and 4 more 7 Cabextract, Ubuntu Linux, Debian Linux and 4 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
In mspack/cab.h in libmspack before 0.8alpha and cabextract before 1.8, the CAB block input buffer is one byte too small for the maximal Quantum block, leading to an out-of-bounds write.
CVE-2018-18557 3 Canonical, Debian, Libtiff 3 Ubuntu Linux, Debian Linux, Libtiff 2024-11-21 6.8 MEDIUM 8.8 HIGH
LibTIFF 3.9.3, 3.9.4, 3.9.5, 3.9.6, 3.9.7, 4.0.0alpha4, 4.0.0alpha5, 4.0.0alpha6, 4.0.0beta7, 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4, 4.0.4beta, 4.0.5, 4.0.6, 4.0.7, 4.0.8 and 4.0.9 (with JBIG enabled) decodes arbitrarily-sized JBIG into a buffer, ignoring the buffer size, which leads to a tif_jbig.c JBIGDecode out-of-bounds write.
CVE-2018-18521 5 Canonical, Debian, Elfutils Project and 2 more 7 Ubuntu Linux, Debian Linux, Elfutils and 4 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.
CVE-2018-18520 5 Canonical, Debian, Elfutils Project and 2 more 7 Ubuntu Linux, Debian Linux, Elfutils and 4 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.
CVE-2018-18506 5 Canonical, Debian, Mozilla and 2 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.
CVE-2018-18505 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 7.5 HIGH 10.0 CRITICAL
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-18504 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
A crash and out-of-bounds read can occur when the buffer of a texture client is freed while it is still in use during graphic operations. This results is a potentially exploitable crash and the possibility of reading from the memory of the freed buffers. This vulnerability affects Firefox < 65.
CVE-2018-18503 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-11-21 6.8 MEDIUM 8.8 HIGH
When JavaScript is used to create and manipulate an audio buffer, a potentially exploitable crash may occur because of a compartment mismatch in some situations. This vulnerability affects Firefox < 65.
CVE-2018-18502 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-11-21 10.0 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 64. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 65.
CVE-2018-18501 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-18500 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-18498 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2018-18497 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2024-11-21 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.
