A double-free vulnerability was found in OpenSSL's PEM_read_bio_ex function. The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the "name" (for example, "CERTIFICATE"), any header data, and the payload data. If the function succeeds, then the "name_out," "header," and "data" arguments are populated with pointers to buffers containing the relevant decoded data. The ca ...

A vulnerability was found in Git. This security issue occurs when feeding a crafted input to "git apply." A path outside the working tree can be overwritten by the user running "git apply."

A vulnerability was found in Git. Using a specially-crafted repository, Git can be tricked into using its local clone optimization even when using a non-local transport. Though Git will abort local clones whose source $GIT_DIR/objects directory contains symbolic links (CVE-2022-39253), the objects directory may still be a symbolic link.

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.

A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the ip_reass() routine while reassembling incoming packets if the first fragment is bigger than the m->m_dat[] buffer. An attacker could use this flaw to crash the QEMU process on the host, resulting in a Denial of Service or potentially executing arbitrary code with privileges o ...

A flaw was found in the way sudo implemented running commands with arbitrary user ID. If a sudoers entry is written to allow the attacker to run a command as any user except root, this flaw can be used by the attacker to bypass that restriction.

CVE-2019-6109 openssh: Missing character encoding in progress display allows for spoofing of scp client output.

It was found that libreoffice was vulnerable to a directory traversal attack which could be used to execute arbitrary macros bundled with a document. An attacker could craft a document, which when opened by LibreOffice, would execute a Python method from a script in any arbitrary file system location, specified relative to the LibreOffice install location.

It was found that ghostscript could leak sensitive operators on the operand stack when a pseudo-operator pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER protection in order to, for example, have access to the file system and execute commands.
