CVE-2019-18679 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.
CVE-2019-18678 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches (between a client and Squid) with attacker-controlled content at arbitrary URLs. Effects are isolated to software between the attacker client and Squid. There are no effects on Squid itself, nor on any upstream servers. The issue is related to a request header containing whitespace between a header name and a colon.
CVE-2019-18677 3 Canonical, Fedoraproject, Squid-cache 3 Ubuntu Linux, Fedora, Squid 2024-11-21 5.8 MEDIUM 6.1 MEDIUM
An issue was discovered in Squid 3.x and 4.x through 4.8 when the append_domain setting is used (because the appended characters do not properly interact with hostname length restrictions). Due to incorrect message processing, it can inappropriately redirect traffic to origins it should not be delivered to.
CVE-2019-18676 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.
CVE-2019-18660 5 Canonical, Fedoraproject, Linux and 2 more 5 Ubuntu Linux, Fedora, Linux Kernel and 2 more 2024-11-21 1.9 LOW 4.7 MEDIUM
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c.
CVE-2019-18609 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.
CVE-2019-18408 4 Canonical, Debian, Libarchive and 1 more 4 Ubuntu Linux, Debian Linux, Libarchive and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
archive_read_format_rar_read_data in archive_read_support_format_rar.c in libarchive before 3.4.0 has a use-after-free in a certain ARCHIVE_FAILED situation, related to Ppmd7_DecodeSymbol.
CVE-2019-18218 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
cdf_read_property_info in cdf.c in file through 5.37 does not restrict the number of CDF_VECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).
CVE-2019-18198 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.3.4, a reference count usage error in the fib6_rule_suppress() function in the fib6 suppression feature of net/ipv6/fib6_rules.c, when handling the FIB_LOOKUP_NOREF flag, can be exploited by a local attacker to corrupt memory, aka CID-ca7a03c41753.
CVE-2019-18197 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2024-11-21 5.1 MEDIUM 7.5 HIGH
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
CVE-2019-17666 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 8.3 HIGH 8.8 HIGH
rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a certain upper-bound check, leading to a buffer overflow.
CVE-2019-17571 6 Apache, Canonical, Debian and 3 more 17 Bookkeeper, Log4j, Ubuntu Linux and 14 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
CVE-2019-17570 5 Apache, Canonical, Debian and 2 more 6 Xml-rpc, Ubuntu Linux, Debian Linux and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
An untrusted deserialization was found in the org.apache.xmlrpc.parser.XmlRpcResponseParser:addResult method of Apache XML-RPC (aka ws-xmlrpc) library. A malicious XML-RPC server could target a XML-RPC client causing it to execute arbitrary code. Apache XML-RPC is no longer maintained and this issue will not be fixed.
CVE-2019-17563 5 Apache, Canonical, Debian and 2 more 11 Tomcat, Ubuntu Linux, Debian Linux and 8 more 2024-11-21 5.1 MEDIUM 7.5 HIGH
When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29, 8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an attacker could perform a session fixation attack. The window was considered too narrow for an exploit to be practical but, erring on the side of caution, this issue has been treated as a security vulnerability.
CVE-2019-17544 2 Canonical, Gnu 2 Ubuntu Linux, Aspell 2024-11-21 6.4 MEDIUM 9.1 CRITICAL
libaspell.a in GNU Aspell before 0.60.8 has a stack-based buffer over-read in acommon::unescape in common/getdata.cpp via an isolated \ character.
CVE-2019-17542 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2024-11-21 7.5 HIGH 9.8 CRITICAL
FFmpeg before 4.2 has a heap-based buffer overflow in vqa_decode_chunk because of an out-of-array access in vqa_decode_init in libavcodec/vqavideo.c.
CVE-2019-17539 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2024-11-21 7.5 HIGH 9.8 CRITICAL
In FFmpeg before 4.2, avcodec_open2 in libavcodec/utils.c allows a NULL pointer dereference and possibly unspecified other impact when there is no valid close function pointer.
CVE-2019-17455 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.
CVE-2019-17451 3 Canonical, Gnu, Opensuse 3 Ubuntu Linux, Binutils, Leap 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as demonstrated by nm.
CVE-2019-17450 3 Canonical, Gnu, Opensuse 3 Ubuntu Linux, Binutils, Leap 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
find_abstract_instance in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted ELF file.
