An exploitable denial-of-service vulnerability exists in the mdnscap binary of the CUJO Smart Firewall running firmware 7003. When parsing labels in mDNS packets, the firewall unsafely handles label compression pointers, leading to an uncontrolled recursion that eventually exhausts the stack, crashing the mdnscap process. An unauthenticated attacker can send an mDNS message to trigger this vulnerability.

blockmason credit-protocol UCAC CreditProtocol.sol executeUcacTx denial of service

** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in blockmason credit-protocol. It has been declared as problematic. Affected by this vulnerability is the function executeUcacTx of the file contracts/CreditProtocol.sol of the component UCAC Handler. The manipulation leads to denial of service. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named 082e01f18707ef995e80ebe97fcedb229a55efc5. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-252799. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

re2c: uncontrolled recursion that causes stack consumption in find_fixed_tags

re2c before 2.0 has uncontrolled recursion that causes stack consumption in find_fixed_tags.

An issue was discovered in the trust-dns-proto crate before 0.5.0-alpha.3 for Rust. There is infinite recursion because DNS message compression is mishandled.

An issue was discovered in the yaml-rust crate before 0.4.1 for Rust. There is uncontrolled recursion during deserialization.

libsass: DoS in Sass::Complex_Selector::perform in ast.hpp and Sass::Inspect::operator in inspect.cpp

LibSass 3.5.4 allows attackers to cause a denial-of-service (uncontrolled recursion in Sass::Complex_Selector::perform in ast.hpp and Sass::Inspect::operator in inspect.cpp).

libsass: parsing component allows attackers to cause denial-of-service

The parsing component in LibSass through 3.5.5 allows attackers to cause a denial-of-service (uncontrolled recursion in Sass::Parser::parse_css_variable_value in parser.cpp).

glibc: uncontrolled recursion in function check_dst_limits_calc_pos_1 in posix/regexec.c

In the GNU C Library (aka glibc or libc6) through 2.29, check_dst_limits_calc_pos_1 in posix/regexec.c has Uncontrolled Recursion, as demonstrated by '(\227|)(\\1\\1|t1|\\\2537)+' in grep.

libexif: Input validation issue resulting in a denial of service

An error when processing the EXIF_IFD_INTEROPERABILITY and EXIF_IFD_EXIF tags within libexif version 0.6.21 can be exploited to exhaust available CPU resources.

Mikrotik RouterOS before 6.42.7 and 6.40.9 is vulnerable to a stack exhaustion vulnerability. An authenticated remote attacker can crash the HTTP server via recursive parsing of JSON.

libsass: illegal address access at Sass::Parser::parse_css_variable_value_token

In LibSass 3.5-stable, there is an illegal address access at Sass::Parser::parse_css_variable_value_token that will lead to a DoS attack.

In libwebm through 2018-10-03, there is an abort caused by libwebm::Webm2Pes::InitWebmParser() that will lead to a DoS attack.

poppler: reachable abort in Object.h

An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file.

binutils: Stack exhaustion in cp-demangle.c allows for denial of service

An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there is a stack consumption problem caused by recursive stack frames: cplus_demangle_type, d_bare_function_type, d_function_type.

kernel: TLB flush happens too late on mremap

Since Linux kernel version 3.2, the mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. This is fixed in the following kernel versions: 4.9.135, 4.14.78, 4.18.16, 4.19.

qpdf: recursive calls can lead to a DoS in libqpdf/QPDFWriter.cc

In QPDF 8.2.1, in libqpdf/QPDFWriter.cc, QPDFWriter::unparseObject and QPDFWriter::unparseChild have recursive calls for a long time, which allows remote attackers to cause a denial of service via a crafted PDF file.

In WAVM through 2018-07-26, a crafted file sent to the WebAssembly Virtual Machine may cause a denial of service (application crash) or possibly have unspecified other impact because Errors::unreachable() is reached.

opensc: Infinite recusrion handling responses from IAS-ECC cards in card-iasecc.c:iasecc_select_file()

Endless recursion when handling responses from an IAS-ECC card in iasecc_select_file in libopensc/card-iasecc.c in OpenSC before 0.19.0-rc1 could be used by attackers able to supply crafted smartcards to hang or crash the opensc library using programs.

libxkbcommon: Endless recursion in xkbcomp/expr.c resulting in a crash

Endless recursion exists in xkbcomp/expr.c in xkbcommon and libxkbcommon before 0.8.1, which could be used by local attackers to crash xkbcommon users by supplying a crafted keymap file that triggers boolean negation.

Lack of administrator control over security vulnerability in client.cgi in Synology SSL VPN Client before 1.2.5-0226 allows remote attackers to conduct man-in-the-middle attacks via the (1) command, (2) hostname, or (3) port parameter.
