CVSS v3.1 |
| The Linux Kernel versions 2.6.38 through 4.14 have a problematic use of pmd_mkdirty() in the touch_pmd() function inside the THP implementation. touch_pmd() can be reached by get_user_pages(). In such case, the pmd will become dirty. This scenario breaks the new can_follow_write_pmd()'s logic - pmd can become dirty without going through a COW cycle. This bug is not as severe as the original "Dirty cow" because an ext4 file (or any other regular file) cannot be mapped using THP. Nevertheless, it does allow us to overwrite read-only huge pages. For example, the zero huge page and sealed shmem files can be overwritten (since their mapping can be populated using THP). Note that after the first write page-fault to the zero page, it will be replaced with a new fresh (and zeroed) thp. |
| The code in Apache Tomcat 9.0.0.M1 to 9.0.0.M11, 8.5.0 to 8.5.6, 8.0.0.RC1 to 8.0.38, 7.0.0 to 7.0.72, and 6.0.0 to 6.0.47 that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own. |
| inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic. |
| inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic. |
| The cirrus_do_copy function in hw/display/cirrus_vga.c in QEMU (aka Quick Emulator), when cirrus graphics mode is VGA, allows local guest OS privileged users to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving blit pitch values. |
| The OAuth implementation in librest before 0.7.93 incorrectly truncates the pointer returned by the rest_proxy_call_get_url function, which allows remote attackers to cause a denial of service (application crash) via running the EnsureCredentials method from the org.gnome.OnlineAccounts.Account interface on an object representing a Flickr account. |
| The kernel-invoked coredump processor in Automatic Bug Reporting Tool (ABRT) does not properly check the ownership of files before writing core dumps to them, which allows local users to obtain sensitive information by leveraging write permissions to the working directory of a crashed application. |
| NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion." |
| Bash before 4.4 allows local users to execute arbitrary commands with root privileges via crafted SHELLOPTS and PS4 environment variables. |
| rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc through 1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC data size during memory allocation for XDR strings, which allows remote attackers to cause a denial of service (memory consumption with no subsequent free) via a crafted UDP packet to port 111, aka rpcbomb. |
| res_query in libresolv in glibc before 2.25 allows remote attackers to cause a denial of service (NULL pointer dereference and process crash). |
| ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation. |
| The AH parser in tcpdump before 4.9.0 has a buffer overflow in print-ah.c:ah_print(). |
| The ARP parser in tcpdump before 4.9.0 has a buffer overflow in print-arp.c:arp_print(). |
| The RTP parser in tcpdump before 4.9.0 has a buffer overflow in print-udp.c:rtp_print(). |
| The UDP parser in tcpdump before 4.9.0 has a buffer overflow in print-udp.c:udp_print(). |
| The TCP parser in tcpdump before 4.9.0 has a buffer overflow in print-tcp.c:tcp_print(). |
| Use-after-free vulnerability in Ghostscript 9.20 might allow remote attackers to execute arbitrary code via vectors related to a reference leak in .setdevice. |
| The BOOTP parser in tcpdump before 4.9.0 has a buffer overflow in print-bootp.c:bootp_print(). |
| The TFTP parser in tcpdump before 4.9.0 has a buffer overflow in print-tftp.c:tftp_print(). |
