CVE-2018-1000005 3 Canonical, Debian, Haxx 3 Ubuntu Linux, Debian Linux, Libcurl 2019-06-18 6.4 MEDIUM 9.1 CRITICAL
libcurl 7.49.0 to and including 7.57.0 contains an out bounds read in code handling HTTP/2 trailers. It was reported (https://github.com/curl/curl/pull/2231) that reading an HTTP/2 trailer could mess up future trailers since the stored size was one byte less than required. The problem is that the code that creates HTTP/1-like headers from the HTTP/2 trailer data once appended a string like `:` to the target buffer, while this was recently changed to `: ` (a space was added after the colon) but the following math wasn't updated correspondingly. When accessed, the data is read out of bounds and causes either a crash or that the (too large) data gets passed to client write. This could lead to a denial-of-service situation or an information disclosure if someone has a service that echoes back or uses the trailers for something.
CVE-2019-9023 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-18 7.5 HIGH 9.8 CRITICAL
An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. A number of heap-based buffer over-read instances are present in mbstring regular expression functions when supplied with invalid multibyte data. These occur in ext/mbstring/oniguruma/regcomp.c, ext/mbstring/oniguruma/regexec.c, ext/mbstring/oniguruma/regparse.c, ext/mbstring/oniguruma/enc/unicode.c, and ext/mbstring/oniguruma/src/utf32_be.c when a multibyte regular expression pattern contains invalid multibyte sequences.
CVE-2019-9022 4 Canonical, Debian, Netapp and 1 more 4 Ubuntu Linux, Debian Linux, Storage Automation Store and 1 more 2019-06-18 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.2. dns_get_record misparses a DNS response, which can allow a hostile DNS server to cause PHP to misuse memcpy, leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries.
CVE-2019-9021 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-18 7.5 HIGH 9.8 CRITICAL
An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. A heap-based buffer over-read in PHAR reading functions in the PHAR extension may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse the file name, a different vulnerability than CVE-2018-20783. This is related to phar_detect_phar_fname_ext in ext/phar/phar.c.
CVE-2019-9020 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-18 7.5 HIGH 9.8 CRITICAL
An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. Invalid input to the function xmlrpc_decode() can lead to an invalid memory access (heap out of bounds read or read after free). This is related to xml_elem_parse_buf in ext/xmlrpc/libxmlrpc/xml_element.c.
CVE-2019-9024 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-18 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1. xmlrpc_decode() can allow a hostile XMLRPC server to cause PHP to read memory outside of allocated areas in base64_decode_xmlrpc in ext/xmlrpc/libxmlrpc/base64.c.
CVE-2015-6031 4 Canonical, Debian, Miniupnp Project and 1 more 5 Ubuntu Linux, Debian Linux, Miniupnpc and 2 more 2019-06-18 6.8 MEDIUM N/A
Buffer overflow in the IGDstartelt function in igd_desc_parse.c in the MiniUPnP client (aka MiniUPnPc) before 1.9.20150917 allows remote UPNP servers to cause a denial of service (application crash) and possibly execute arbitrary code via an "oversized" XML element name.
CVE-2019-9917 3 Canonical, Fedoraproject, Znc 3 Ubuntu Linux, Fedora, Znc 2019-06-14 4.0 MEDIUM 6.5 MEDIUM
ZNC before 1.7.3-rc1 allows an existing remote user to cause a Denial of Service (crash) via invalid encoding.
CVE-2019-7524 4 Canonical, Debian, Dovecot and 1 more 4 Ubuntu Linux, Debian Linux, Dovecot and 1 more 2019-06-13 7.2 HIGH 7.8 HIGH
In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components.
CVE-2019-3814 3 Canonical, Dovecot, Opensuse 3 Ubuntu Linux, Dovecot, Leap 2019-06-13 4.9 MEDIUM 6.8 MEDIUM
It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users.
CVE-2015-1472 2 Canonical, Gnu 2 Ubuntu Linux, Glibc 2019-06-13 7.5 HIGH N/A
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call.
CVE-2014-9761 5 Canonical, Fedoraproject, Gnu and 2 more 9 Ubuntu Linux, Fedora, Glibc and 6 more 2019-06-13 7.5 HIGH 9.8 CRITICAL
Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function.
CVE-2016-10714 2 Canonical, Zsh 2 Ubuntu Linux, Zsh 2019-06-11 7.5 HIGH 9.8 CRITICAL
In zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support PATH_MAX characters.
CVE-2014-10071 2 Canonical, Zsh 2 Ubuntu Linux, Zsh 2019-06-11 7.5 HIGH 9.8 CRITICAL
In exec.c in zsh before 5.0.7, there is a buffer overflow for very long fds in the ">& fd" syntax.
CVE-2018-11469 2 Canonical, Haproxy 2 Ubuntu Linux, Haproxy 2019-06-11 4.3 MEDIUM 5.9 MEDIUM
Incorrect caching of responses to requests including an Authorization header in HAProxy 1.8.0 through 1.8.9 (if cache enabled) allows attackers to achieve information disclosure via an unauthenticated remote request, related to the proto_http.c check_request_for_cacheability function.
CVE-2018-8789 3 Canonical, Debian, Freerdp 3 Ubuntu Linux, Debian Linux, Freerdp 2019-06-03 5.0 MEDIUM 7.5 HIGH
FreeRDP prior to version 2.0.0-rc4 contains several Out-Of-Bounds Reads in the NTLM Authentication module that results in a Denial of Service (segfault).
CVE-2018-8788 3 Canonical, Debian, Freerdp 3 Ubuntu Linux, Debian Linux, Freerdp 2019-06-03 7.5 HIGH 9.8 CRITICAL
FreeRDP prior to version 2.0.0-rc4 contains an Out-Of-Bounds Write of up to 4 bytes in function nsc_rle_decode() that results in a memory corruption and possibly even a remote code execution.
CVE-2019-9675 3 Canonical, Opensuse, Php 3 Ubuntu Linux, Leap, Php 2019-06-03 6.8 MEDIUM 8.1 HIGH
** DISPUTED ** An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible."
CVE-2019-9637 5 Canonical, Debian, Netapp and 2 more 5 Ubuntu Linux, Debian Linux, Storage Automation Store and 2 more 2019-06-03 5.0 MEDIUM 7.5 HIGH
An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.
CVE-2018-1000135 2 Canonical, Gnome 2 Ubuntu Linux, Networkmanager 2019-06-03 5.0 MEDIUM 7.5 HIGH
GNOME NetworkManager version 1.10.2 and earlier contains a Information Exposure (CWE-200) vulnerability in DNS resolver that can result in Private DNS queries leaked to local network's DNS servers, while on VPN. This vulnerability appears to have been fixed in Some Ubuntu 16.04 packages were fixed, but later updates removed the fix. cf. https://bugs.launchpad.net/ubuntu/+bug/1754671 an upstream fix does not appear to be available at this time.
