CVE-2020-2601 6 Canonical, Debian, Netapp and 3 more 23 Ubuntu Linux, Debian Linux, Active Iq Unified Manager and 20 more 2021-03-04 4.3 MEDIUM 6.8 MEDIUM
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Security). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Kerberos to compromise Java SE, Java SE Embedded. While the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 6.8 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).

CVE-2020-2654 7 Canonical, Debian, Mcafee and 4 more 23 Ubuntu Linux, Debian Linux, Epolicy Orchestrator and 20 more 2021-03-04 4.3 MEDIUM 3.7 LOW
Vulnerability in the Java SE product of Oracle Java SE (component: Libraries). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE. Note: This vulnerability can only be exploited by supplying data to APIs in the specified Component without using Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).

The vsf_filename_passes_filter function in ls.c in vsftpd before 2.3.3 allows remote authenticated users to cause a denial of service (CPU consumption and process slot exhaustion) via crafted glob expressions in STAT commands in multiple FTP sessions, a different vulnerability than CVE-2010-2632.
CVE-2020-2590 7 Canonical, Debian, Mcafee and 4 more 24 Ubuntu Linux, Debian Linux, Epolicy Orchestrator and 21 more 2021-02-26 4.3 MEDIUM 3.7 LOW
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Security). Supported versions that are affected are Java SE: 7u241, 8u231, 11.0.5 and 13.0.1; Java SE Embedded: 8u231. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Kerberos to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. CVSS 3.0 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

CVE-2020-12663 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-02-17 5.0 MEDIUM 7.5 HIGH
Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers.
CVE-2019-12519 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-02-11 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.
CVE-2019-12520 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2021-02-11 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI.
CVE-2019-13619 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-02-10 5.0 MEDIUM 7.5 HIGH
In Wireshark 3.0.0 to 3.0.2, 2.6.0 to 2.6.9, and 2.4.0 to 2.4.15, the ASN.1 BER dissector and related dissectors could crash. This was addressed in epan/asn1.c by properly restricting buffer increments.
CVE-2019-1010319 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-02-09 4.3 MEDIUM 5.5 MEDIUM
WavPack 5.1.0 and earlier is affected by: CWE-457: Use of Uninitialized Variable. The impact is: Unexpected control flow, crashes, and segfaults. The component is: ParseWave64HeaderConfig (wave64.c:211). The attack vector is: Maliciously crafted .wav file. The fixed version is: After commit https://github.com/dbry/WavPack/commit/33a0025d1d63ccd05d9dbaa6923d52b1446a62fe.
CVE-2019-12524 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2021-02-09 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintainer. This rule is implemented via url_regex. The handler for url_regex rules URL decodes an incoming request. This allows an attacker to encode their URL to bypass the url_regex check, and gain access to the blocked resource.
CVE-2018-17095 2 Audio File Library Project, Canonical 2 Audio File Library, Ubuntu Linux 2021-02-09 6.8 MEDIUM 8.8 HIGH
An issue has been discovered in mpruett Audio File Library (aka audiofile) 0.3.6, 0.3.5, 0.3.4, 0.3.3, 0.3.2, 0.3.1, 0.3.0. A heap-based buffer overflow in Expand3To4Module::run has occurred when running sfconvert.
CVE-2018-5785 3 Canonical, Debian, Uclouvain 3 Ubuntu Linux, Debian Linux, Openjpeg 2021-02-03 4.3 MEDIUM 6.5 MEDIUM
In OpenJPEG 2.3.0, there is an integer overflow caused by an out-of-bounds left shift in the opj_j2k_setup_encoder function (openjp2/j2k.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
