The CBC padding operations were not constant time and as a result would leak the length of the plaintext values which were being padded to an attacker running a side channel attack via shared resources such as cache or branch predictor. No information about the contents was leaked, but the length alone might be used to make inferences about the contents. This issue affects TLS CBC
jp2/opj_decompress.c in OpenJPEG through 2.3.1 has a use-after-free that can be triggered if there is a mix of valid and invalid files in a directory operated on by the decompressor. Triggering a double-free may also be possible. This is related to calling opj_image_destroy twice (CVE-2020-15389).
A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3 that makes it is possible for an attacker to forge a secure or host-only cookie prefix (CVE-2020-8184). References:
An out-of-bounds read was discovered in PCRE before 10.34 when the pattern \X is JIT compiled and used to match specially crafted subjects in non-UTF mode. Applications that use PCRE to parse untrusted input may be vulnerable to this flaw, which would allow an attacker to crash the application. The flaw occurs in do_extuni_no_utf in pcre2_jit_compile.c. (CVE-2019-20454)
The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue. (CVE-2020-12695).
Netwide Assembler (NASM) 2.13 has a stack-based buffer over-read in the disasm function of the disasm/disasm.c file. Remote attackers could leverage this vulnerability to cause a denial of service or possibly have unspecified other impact via a crafted ELF file (CVE-2018-10254).
The server in Chocolate Doom 3.0.0 doesn't validate the user-controlled num_players value, leading to a buffer overflow. A malicious user can overwrite the server's stack (CVE-2020-14983). References:
This update fixes a recently reported cross-site scripting (XSS) vulnerability via HTML messages with malicious svg/namespace. References: - https://bugs.mageia.org/show_bug.cgi?id=26905
If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection (CVE-2020-12398). When browsing a malicious page, a race condition in our SharedWorkerService
Mat_VarReadNextInfo4 in mat4.c in MATIO 1.5.17 omits a certain '\0' character, leading to a heap-based buffer over-read in strdup_vprintf when uninitialized memory is accessed. (CVE-2019-17533) References:
Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543) Cleanup errors in some Intel(R) Processors may allow an authenticated user
It was discovered that FreeRDP incorrectly handled certain memory operations. A remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly exeucte arbitrary code.
A use-after-free vulnerability was found in xerces-c in the way an XML document is processed via the SAX API. Applications that process XML documents with an external Document Type Definition (DTD) may be vulnerable to this flaw. A remote attacker could exploit this flaw by creating a specially crafted XML file that would crash the application or
In cloud-init, relies on Mersenne Twister for a random password, which makes it easier for attackers to predict passwords, because rand_str in cloudinit/util.py calls the random.choice function (CVE-2020-8631). In cloud-init, rand_user_password in cloudinit/config/cc_set_passwords.py
The updated packages fix security vulnerabilities: A stack-based buffer over-read in the PdfEncryptMD5Base::ComputeEncryptionKey() function in PdfEncrypt.cpp in PoDoFo 0.9.6-rc1 could be leveraged by remote attackers to cause a denial-of-service via a crafted pdf file. (CVE-2018-12983)
Updated mbedtls packages fix security vulnerabilities Fix a side channel vulnerability in modular exponentiation that could reveal an RSA private key used in a secure enclave.
Updated mediawiki packages fix security vulnerability: In MediaWiki before 1.31.8, private wikis behind a caching server using the img_auth.php image authorization security feature may have had their files cached publicly, so any unauthorized user could view them. This
Advisory text to describe the update. Wrap lines at ~75 chars. A stack-based buffer over-read exists in FoFiTrueType::dumpString in fofi/FoFiTrueType.cc in Xpdf 4.01.01. It can, for example, be triggered by sending crafted TrueType data in a PDF document to the pdftops tool.
Updated ffmpeg packages fix security vulnerabilities: This update provides ffmpeg version 4.1.6, which fixes several security vulnerabilities and other bugs which were corrected upstream.
Updated samba packages fix security vulnerabilities: Andrew Bartlett discovered that Samba incorrectly handled certain LDAP queries. A remote attacker could use this issue to cause Samba to crash, resulting in a denial of service, or possibly execute arbitrary code
