USN-6885-3: Apache HTTP Server vulnerabilities

Read Time:48 Second

USN-6885-1 fixed several vulnerabilities in Apache. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

Original advisory details:

Orange Tsai discovered that the Apache HTTP Server mod_rewrite module
incorrectly handled certain substitutions. A remote attacker could
possibly use this issue to execute scripts in directories not directly
reachable by any URL, or cause a denial of service. Some environments
may require using the new UnsafeAllow3F flag to handle unsafe
substitutions. (CVE-2024-38474, CVE-2024-38475)

Orange Tsai discovered that the Apache HTTP Server incorrectly handled
certain response headers. A remote attacker could possibly use this issue
to obtain sensitive information, execute local scripts, or perform SSRF
attacks. (CVE-2024-38476)

Orange Tsai discovered that the Apache HTTP Server mod_proxy module
incorrectly handled certain requests. A remote attacker could possibly use
this issue to cause the server to crash, resulting in a denial of service.
(CVE-2024-38477)

USN-7018-1: OpenSSL vulnerabilities

Read Time:1 Minute, 5 Second

Robert Merget, Marcus Brinkmann, Nimrod Aviram, and Juraj Somorovsky
discovered that certain Diffie-Hellman ciphersuites in the TLS
specification and implemented by OpenSSL contained a flaw. A remote
attacker could possibly use this issue to eavesdrop on encrypted
communications. This was fixed in this update by removing the insecure
ciphersuites from OpenSSL. (CVE-2020-1968)

Paul Kehrer discovered that OpenSSL incorrectly handled certain input
lengths in EVP functions. A remote attacker could possibly use this issue
to cause OpenSSL to crash, resulting in a denial of service.
(CVE-2021-23840)

Elison Niven discovered that OpenSSL incorrectly handled the c_rehash
script. A local attacker could possibly use this issue to execute arbitrary
commands when c_rehash is run. (CVE-2022-1292)

Chancen and Daniel Fiala discovered that OpenSSL incorrectly handled the
c_rehash script. A local attacker could possibly use this issue to execute
arbitrary commands when c_rehash is run. (CVE-2022-2068)

It was discovered that OpenSSL incorrectly handled excessively large
Diffie-Hellman parameters. An attacker could possibly use this issue
to cause a denial of service. (CVE-2023-3446)

Bahaa Naamneh discovered that OpenSSL incorrectly handled certain malformed
PKCS12 files. A remote attacker could possibly use this issue to cause
OpenSSL to crash, resulting in a denial of service. (CVE-2024-0727)

USN-7000-2: Expat vulnerabilities

Read Time:31 Second

USN-7000-1 fixed vulnerabilities in Expat. This update
provides the corresponding updates for Ubuntu 22.04 LTS.

Original advisory details:

Shang-Hung Wan discovered that Expat did not properly handle certain
function calls when a negative input length was provided. An attacker
could use this issue to cause a denial of service or possibly execute
arbitrary code. (CVE-2024-45490)

Shang-Hung Wan discovered that Expat did not properly handle the
potential for an integer overflow on 32-bit platforms. An attacker
could use this issue to cause a denial of service or possibly execute
arbitrary code. (CVE-2024-45491, CVE-2024-45492)

provides the corresponding updates for Ubuntu 24.04 LTS.

Original advisory details:

Shang-Hung Wan discovered that Expat, contained within the xmltok library,
did not properly handle certain function calls when a negative input
length was provided. An attacker could use this issue to cause a denial of
service or possibly execute arbitrary code. (CVE-2024-45490)

Shang-Hung Wan discovered that Expat, contained within the xmltok library,
did not properly handle the potential for an integer overflow on 32-bit
