A flaw was found in expat. Passing malformed 2- and 3-byte UTF-8 sequences (for example, from start tag names) to the XML processing application on top of expat can lead to arbitrary code execution. This issue is dependent on how invalid UTF-8 is handled inside the XML processor.

A flaw was found in expat. Passing one or more namespace separator characters in the "xmlns[:prefix]" attribute values made expat send malformed tag names to the XML processor on top of expat. This issue causes arbitrary code execution depending on how unexpected cases are handled inside the XML processor.

An integer overflow was found in expat. The issue occurs in storeRawNames() by abusing the mbuffer expansion logic to allow allocations very close to INTMAX and out-of-bounds heap writes. This flaw can cause a denial of service or potentially arbitrary code execution.

cURL libcurl is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the tftpreceivepacket function. By sending specially-crafted request containing an OACK without the BLKSIZE option, a remote attacker could overflow a buffer and execute arbitrary code on the system.

A buffer overflow flaw in httpd's lua module could allow an out-of-bounds write. An attacker who is able to submit a crafted request to an httpd instance that is using the lua module may be able to cause an impact to confidentiality, integrity, and/or availability.

Disabling mod_lua and restarting httpd will mitigate this flaw. See https://access.redhat.com/articles/10649 for more information.

Use After Free
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

A read-after-free vulnerability was discovered in Apache httpd, in modhttp2. A specially crafted http/2 client session could cause the server to read memory that was previously freed during connection shutdown, potentially leading to a crash.

1 / 4

Remedy

This flaw is only exploitable if Apache httpd is configured to respond to HTTP/2 requests, which is done by including "h2" or "h2c" in the "Protocols" list in a configuration file. The following command can be used to search for possible vulnerable configurations: grep -R '^\s*Protocols\>.*\<h2\>' /etc/httpd/ See https://httpd.apache.org/docs/2.4/mod/mod_http2.html

Remedy

Unpatched servers can disable the h2/h2c protocol.

Impact The HTML Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG files embedded using data URIs.

Users that employ the HTML cleaner in a security relevant context should upgrade to lxml 4.6.5.

Patches The issue has been resolved in lxml 4.6.5.

Workarounds None.
