Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) SQL injection (CVE-ID: CVE-2024-27304)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data when handling overly large queries that exceed 4 GB in size. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
2) SQL injection (CVE-ID: CVE-2024-27289)
The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data under certain conditions. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability requires that all of the following conditions are met: the non-default simple protocol is used; a placeholder for a numeric value must be immediately preceded by a minus; there must be a second placeholder for a string value after the first placeholder; both must be on the same line; and both parameter values must be user-controlled.
3) Use-after-free (CVE-ID: CVE-2019-13224)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the onig_new_deluxe() function in regext.c in Oniguruma library when processing regular expressions. A remote attacker can pass specially crafted input to the application using the vulnerable library version, trigger use-after-free error and perform denial of service attack or execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Resource exhaustion (CVE-ID: CVE-2019-16163)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.
5) Integer overflow (CVE-ID: CVE-2019-19012)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to integer overflow in the "search_in_range" function in "regexec.c". A remote attacker can use a specially crafted regular expression, trigger out-of-bounds read and cause a denial-of-service or information disclosure on the target system.
6) Buffer Over-read (CVE-ID: CVE-2019-19203)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the "gb18030_mbc_enc_len" function in "gb18030.c" file due to the UChar pointer is dereferenced without checking if it passed the end of the matched string. A remote attacker can cause a denial of service condition on the target system.
7) Buffer Over-read (CVE-ID: CVE-2019-19204)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in the "fetch_interval_quantifier" function (formerly known as fetch_range_quantifier) in "regparse.c" file due to the PFETCH is called without checking PEND. A remote attacker can cause a denial of service condition on the target system.8) Out-of-bounds read (CVE-ID: CVE-2020-28241)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to heap-based buffer over-read in dump_entry_data_list in maxminddb.c. A remote attacker can perform a denial of service attack.
9) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2021-35937)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability exist due to race condition. A local privileged user can bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges.
10) Link following (CVE-ID: CVE-2021-35938)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability occurs when rpm sets the desired permissions and credentials after installing a file. A local privileged user can use this flaw to exchange the original file with a symbolic link to a security-critical file and escalate their privileges on the system.
11) Link following (CVE-ID: CVE-2021-35939)
The vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability exist due to fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only implemented for the parent directory of the file to be created. A local privileged user who owns another ancestor directory could potentially use this flaw to gain root privileges.
12) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
13) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2024-0553)
The vulnerability allows a remote attacker to perform timing attack.
The vulnerability exists due to the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. A remote attacker can perform timing sidechannel attack in RSA-PSK key exchange.
Note, the vulnerability exists due to incomplete fox for #VU83316 (CVE-2023-5981).
