CVE-2017-15873 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
The get_next_block function in archival/libarchive/decompress_bunzip2.c in BusyBox 1.27.2 has an Integer Overflow that may lead to a write access violation.
CVE-2017-15868 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.
CVE-2017-15715 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 6.8 MEDIUM 8.1 HIGH
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.
CVE-2017-15710 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all.
CVE-2017-15705 4 Apache, Canonical, Debian and 1 more 7 Spamassassin, Ubuntu Linux, Debian Linux and 4 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. The issue is possibly a bug or design decision in HTML::Parser that specifically impacts the way Apache SpamAssassin uses the module with poorly formed html. The exploit has been seen in the wild but not believed to have been purposefully part of a Denial of Service attempt. We are concerned that there may be attempts to abuse the vulnerability in the future.
CVE-2017-15422 5 Canonical, Debian, Google and 2 more 7 Ubuntu Linux, Debian Linux, Chrome and 4 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
Integer overflow in international date handling in International Components for Unicode (ICU) for C/C++ before 60.1, as used in V8 in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
CVE-2017-15298 2 Canonical, Git-scm 2 Ubuntu Linux, Git 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
Git through 2.14.2 mishandles layers of tree objects, which allows remote attackers to cause a denial of service (memory consumption) via a crafted repository, aka a Git bomb. This can also have an impact of disk consumption; however, an affected process typically would not survive its attempt to build the data structure in memory before writing to disk.
CVE-2017-15281 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 6.8 MEDIUM 8.8 HIGH
ReadPSDImage in coders/psd.c in ImageMagick 7.0.7-6 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file, related to "Conditional jump or move depends on uninitialised value(s)."
CVE-2017-15275 4 Canonical, Debian, Redhat and 1 more 6 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory.
CVE-2017-15218 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-2 has a memory leak in ReadOneJNGImage in coders/png.c.
CVE-2017-15217 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
ImageMagick 7.0.7-2 has a memory leak in ReadSGIImage in coders/sgi.c.
CVE-2017-15132 3 Canonical, Debian, Dovecot 3 Ubuntu Linux, Debian Linux, Dovecot 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in dovecot 2.0 up to 2.2.33 and 2.3.0. An abort of SASL authentication results in a memory leak in dovecot's auth client used by login processes. The leak has impact in high performance configuration where same login processes are reused and can cause the process to crash due to memory exhaustion.
CVE-2017-15130 3 Canonical, Debian, Dovecot 3 Ubuntu Linux, Debian Linux, Dovecot 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
A denial of service flaw was found in dovecot before 2.2.34. An attacker able to generate random SNI server names could exploit TLS SNI configuration lookups, leading to excessive memory usage and the process to restart.
CVE-2017-15129 4 Canonical, Fedoraproject, Linux and 1 more 20 Ubuntu Linux, Fedora, Linux Kernel and 17 more 2024-11-21 4.9 MEDIUM 4.7 MEDIUM
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.
CVE-2017-15119 4 Canonical, Debian, Qemu and 1 more 4 Ubuntu Linux, Debian Linux, Qemu and 1 more 2024-11-21 5.0 MEDIUM 5.8 MEDIUM
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS.
CVE-2017-15118 3 Canonical, Qemu, Redhat 3 Ubuntu Linux, Qemu, Enterprise Linux 2024-11-21 7.5 HIGH 8.3 HIGH
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
CVE-2017-15115 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 7.2 HIGH 7.8 HIGH
The sctp_do_peeloff function in net/sctp/socket.c in the Linux kernel before 4.14 does not check whether the intended netns is used in a peel-off action, which allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via crafted system calls.
CVE-2017-15105 3 Canonical, Debian, Nlnetlabs 3 Ubuntu Linux, Debian Linux, Unbound 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
A flaw was found in the way unbound before 1.6.8 validated wildcard-synthesized NSEC records. An improperly validated wildcard NSEC record could be used to prove the non-existence (NXDOMAIN answer) of an existing wildcard record, or trick unbound into accepting a NODATA proof.
CVE-2017-15102 3 Canonical, Linux, Redhat 3 Ubuntu Linux, Linux Kernel, Enterprise Linux 2024-11-21 6.9 MEDIUM 6.3 MEDIUM
The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel before 4.8.1 allows local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference.
CVE-2017-15033 2 Canonical, Imagemagick 2 Ubuntu Linux, Imagemagick 2024-11-21 5.0 MEDIUM 7.5 HIGH
ImageMagick version 7.0.7-2 contains a memory leak in ReadYUVImage in coders/yuv.c.
