A type confusion vulnerability was found in OpenSSL when OpenSSL X.400 addresses processing inside an X.509 GeneralName. When CRL checking is enabled (for example, the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or cause a denial of service. In most cases, the attack re ...

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.

The polkit package is designed to define and handle policies that allow unprivileged processes to communicate with privileged processes on a Linux system. Pkexec, part of polkit, is a tool that allows the user to execute commands as another user according to the polkit policy definitions using the setuid feature. The vulnerability found in pkexec allows an unprivileged local attacker to escalate p ...

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 use-after-free vulnerability was found in OpenSSL's BIO_new_NDEF function. The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be called directly by end-user applications. The function receives a BIO from the caller, prepends a new ...

A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number of trial messages for decryption. This issue affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP, and RSASVE.

The host is installed with samba version 4.x and is prone to a denial of service vulnerability. A flaw is present in samba which fails to handle character conversion at log level 3 or above. An unauthenticated attacker could use this flaw to cause samba to crash.

The host is installed with MySQL 5.1.73 and earlier on Centos 6, mariadb 5.5.50 and earlier on Centos 7 or MySQL 5.0.95 and earlier on Centos 5 and is prone to a privilege escalation vulnerability. A flaw is present in the application, which fails to properly handle MySQL logging functions. Successful exploitation allows remote attackers to execute arbitrary code.

A flaw was found in BIND, where it does not sufficiently limit the number of fetches that can be performed while processing a referral response. This flaw allows an attacker to cause a denial of service attack. The attacker can also exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor.
