This update provides security bug fixes and minor enhancements. Limit the size of calculations performed by mbedtls_mpi_exp_mod to MBEDTLS_MPI_MAX_SIZE to prevent a potential denial of service when generating Diffie-Hellman key pairs.
This code was vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both (CVE-2019-9512).
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME.
Vulnerabilities in the Oracle VM VirtualBox are fixed in version 6.1.16. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability which can lead to execute code in the context of the hypervisor. (CVE-2020-14872).
The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited
A heap-buffer overwrites error was discovered in lib/openjp2/mqc.c in OpenJPEG 2.3.1. The vulnerability causes an out-of-bounds write, which may lead to remote denial of service or possibly remote code execution (CVE-2020-27814). A flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass
There's a flaw in jasper's jpc encoder in versions prior to 2.0.23. Crafted input provided to jasper by an attacker could cause an arbitrary out-of-bounds write. This could potentially affect data confidentiality, integrity, or application availability (CVE-2020-27828).
When a BigInt was right-shifted the backing store was not properly cleared, allowing uninitialized memory to be read (CVE-2020-16042). Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow in WebGL on some video drivers (CVE-2020-26971).

dpic 2019.06.20 has a Stack-based Buffer Overflow in the wfloat() function in main.c. (CVE-2019-13989) References: - https://bugs.mageia.org/show_bug.cgi?id=27759 - https://security-tracker.debian.org/tracker/CVE-2019-13989
In sam2p 0.49.3, a heap-based buffer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp. (CVE-2017-14628). In sam2p 0.49.3, the in_xpm_reader function in in_xpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array
Multiple vulnerabilities have been discovered in Bitcoin. In Bitcoin Core 0.18.0, bitcoin-qt stores wallet.dat data unencrypted in memory. Upon a crash, it may dump a core file. If a user were to mishandle a core file, an attacker can reconstruct the user's
Jupyter Notebook before version 6.1.5 has an Open redirect vulnerability. A maliciously crafted link to a notebook server could redirect the browser to a different website. All notebook servers are technically affected, however, these maliciously crafted links can only be reasonably made for known notebook server hosts. A link to your notebook server may appear safe, but ultimately redirect to a spoofed server on the public internet. (CVE-2020-26215) References: - https://bugs.mageia.org/show_bug.cgi?id=27705 - https://www.debian.org/lts/security/2020/dla-2477
A flaw was found in the X.Org Server. An out-of-bounds access in the XkbSetMap function may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability (CVE-2020-14360).
The updated packages fix some problems found in version 86 and security vulnerabilities. References: - https://bugs.mageia.org/show_bug.cgi?id=27630
scan.c in x11vnc 0.9.16 uses IPC_CREAT|0777 in shmget calls, which allows access by actors other than the current user. (CVE-2020-29074) References: - https://bugs.mageia.org/show_bug.cgi?id=27684
Filename manipulation vulnerabilities (CVE-2020-28948 / CVE-2020-28949) Updated also Archive_Tar to 1.4.11. References: - https://bugs.mageia.org/show_bug.cgi?id=27664
In Oniguruma, an attacker able to supply a regular expression for compilation may be able to overflow a buffer by one byte in concat_opt_exact_str in src/regcomp.c (CVE-2020-26159). References:
It was discovered that incorrectly handled certain ZIP files. An attacker could possibly use this issue to cause a denial of service (CVE-2019-9674). It was discovered that Python documentation had a misleading information. A security issue could be possibly caused by wrong assumptions of this
When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to stack corruption that may be exploitable (CVE-2020-26970).
