A flaw was found in the way NSS verifies certificates. That will happen both when client reads the Certificate message from the server or when server is configured to ask for client certificates and then receives one.

Firefox is not vulnerable as it uses the mozilla::pkix for certificate verification. Crucially, NSS fully parses the certificate before any other checks, so disabled signature methods or certificate types don't impact exploitability.

Any TLS and DTLS client that does use NSS built in certificate verification routines is vulnerable as well as any server that has certificate based client authentication enabled.

But the issue is not limited to TLS, any applications that use certificate verification are vulnerable, S/MIME is impacted too.

A flaw was found in rpm. Given an RPM package signed by a trusted key, it is possible to modify it such that it still passes signature checks, but installing it corrupts the rpmdb.

A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user calls the CASENDMSG ioctl. This flaw allows a local user of the host machine to crash the system or escalate privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

DISPUTED An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It permits the visual reordering of characters via control sequences, which can be used to craft source code that renders different logic than the logical ordering of tokens ingested by compilers and interpreters. Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the following alternative approach to presenting this concern. An issue is noted in the nature of international text that can affect applications that implement support for The Unicode Standard and the Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-right and right-to-left characters, the visual order of tokens may be different from their logical order. Additionally, control characters needed to fully support the requirements of bidirectional text can further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such that the ordering of tokens perceived by human reviewers does not match what will be processed by a compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.

A denial of service flaw was found in fusedogetattr in fs/fuse/dir.c in the kernel side of the FUSE filesystem in the Linux kernel. A local user could use this flaw to crash the system.

A flaw memory leak in the Linux kernel performance monitoring subsystem was found in the way if using PERFEVENTIOCSETFILTER. A local user could use this flaw to starve the resources causing denial of service.

A flaw was found in StarWind Stack. The endpoint for setting a new password doesn’t check the current username and old password. An attacker could reset any local user password (including system/administrator user) using any available user This affects StarWind SAN and NAS v0.2 build 1633.

A flaw was found in the REST API in StarWind Stack. REST command, which manipulates a virtual disk, doesn’t check input parameters. Some of them go directly to bash as part of a script. An attacker with non-root user access can inject arbitrary data into the command that will be executed with root privileges. This affects StarWind SAN and NAS v0.2 build 1633.
