| CVE-2018-19059 | 2 Canonical, Freedesktop | 2 Ubuntu Linux, Poppler | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Poppler 0.71.0. There is a out-of-bounds read in EmbFile::save2 in FileSpec.cc, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating embedded files before save attempts. | |||||
| CVE-2018-19058 | 4 Canonical, Debian, Freedesktop and 1 more | 6 Ubuntu Linux, Debian Linux, Poppler and 3 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file. | |||||
| CVE-2018-18955 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 4.4 MEDIUM | 7.0 HIGH |
| In the Linux kernel 4.15.x through 4.19.x before 4.19.2, map_write() in kernel/user_namespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace, as demonstrated by reading /etc/shadow. This occurs because an ID transformation takes place properly for the namespaced-to-kernel direction but not for the kernel-to-namespaced direction. | |||||
| CVE-2018-18954 | 3 Canonical, Opensuse, Qemu | 3 Ubuntu Linux, Leap, Qemu | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| The pnv_lpc_do_eccb function in hw/ppc/pnv_lpc.c in Qemu before 3.1 allows out-of-bounds write or read access to PowerNV memory. | |||||
| CVE-2018-18898 | 4 Bestpractical, Canonical, Debian and 1 more | 4 Request Tracker, Ubuntu Linux, Debian Linux and 1 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The email-ingestion feature in Best Practical Request Tracker 4.1.13 through 4.4 allows denial of service by remote attackers via an algorithmic complexity attack on email address parsing. | |||||
| CVE-2018-18897 | 4 Canonical, Debian, Freedesktop and 1 more | 10 Ubuntu Linux, Debian Linux, Poppler and 7 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in GfxState.cc, as demonstrated by pdftocairo. | |||||
| CVE-2018-18873 | 4 Canonical, Debian, Jasper Project and 1 more | 5 Ubuntu Linux, Debian Linux, Jasper and 2 more | 2024-11-21 | 4.3 MEDIUM | 5.5 MEDIUM |
| An issue was discovered in JasPer 2.0.14. There is a NULL pointer dereference in the function ras_putdatastd in ras/ras_enc.c. | |||||
| 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. | |||||
