"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0076 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-13224:
    A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause
    information disclosure, denial of service, or possibly code execution by providing a crafted regular
    expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that
    gets handled by onig_new_deluxe(). Oniguruma issues often affect Ruby, as well as common optional
    libraries for PHP and Rust.

    CVE-2019-16163:
    Oniguruma before 6.9.3 allows Stack Exhaustion in regcomp.c because of recursion in regparse.c.

    CVE-2019-19012:
    An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads
    to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only
    affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information
    disclosure, or possibly have unspecified other impact, via a crafted regular expression.

    CVE-2019-19203:
    An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function gb18030_mbc_enc_len in file
    gb18030.c, a UChar pointer is dereferenced without checking if it passed the end of the matched string.
    This leads to a heap-based buffer over-read.

    CVE-2019-19204:
    An issue was discovered in Oniguruma 6.x before 6.9.4_rc2. In the function fetch_interval_quantifier
    (formerly known as fetch_range_quantifier) in regparse.c, PFETCH is called without checking PEND. This
    leads to a heap-based buffer over-read.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

number.");
