Multiple vulnerabilities have been fixed in the Python3 interpreter. CVE-2015-20107 . - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3980-1
A defect was discovered in the Python âsslâ module where there is a memory race condition with the ssl.SSLContext methods âcert_store_stats()â and âget_ca_certs()â. The race condition can be triggered if the methods are called at the same time as certificates are loaded into the SSLContext, such as during the TLS handshake with a . MGASA-2024-0317 - Updated python3 packages fix security vulnerabilities Publication date: 27 Sep 2024 URL: https://advisories.mageia.org/MGASA-2024-0317.html Type: security Affected Mageia releases: 9 CVE: CVE-2024-0397, CVE-2024-4032, CVE-2024-6923, CVE-2024-8088, CVE-2024-6232, CVE-2024-7592, CVE-2015-2104, CVE-2023-27043 A defect was discovered in the Python âsslâ module where there is a memory race condition with the ssl.SSLContext methods âcert_store_stats()â and âget_ca_certs()â. The race condition can be triggered if the methods are called at the same time as certificates are loaded into the SSLContext, such as during the TLS handshake with a certificate directory configured. (CVE-2024-0397) The âipaddressâ module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as âglobally reachableâ or âprivateâ. This affected the is_private and is_global properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network classes, where values wouldnât be returned in accordance with the latest information from the IANA Special-Purpose Address Registries. (CVE-2024-4032) The email module didnât properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. (CVE-2024-6923) When iterating over names of entries in a zip archive (for example, methods of "zipfile.Path" like "namelist()", "iterdir()", etc) the process can be put into an infinite loop with a maliciously crafted zip archive. This defectapplies when reading only metadata or extracting the contents of the zip archive. Programs that are not handling user-controlled zip archives are not affected. (CVE-2024-8088) Regular expressions that allowed excessive backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar archives. (CVE-2024-6232) When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value. (CVE-2024-7592) Urlparse insufficient validation leads to open redirect. (CVE-2015-2104) The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python.

Summary: Updated gnutls packages that fix two security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS). It was discovered that GnuTLS did not correctly handle certain errors that could occur during the verification of an X.509 certificate, causing it to incorrectly report a successful verification. An attacker could use this flaw to create a specially crafted certificate that could be accepted by GnuTLS as valid for a site chosen by the attacker. (CVE-2014-0092) A flaw was found in the way GnuTLS handled version 1 X.509 certificates. An attacker able to obtain a version 1 certificate from a trusted certificate authority could use this flaw to issue certificates for other sites that would be accepted by GnuTLS as valid.(CVE-2009-5138) The CVE-2014-0092 issue was discovered by Nikos Mavrogiannopoulos of the Red Hat Security Technologies Team. Users of GnuTLS are advised to upgrade to these updated packages, which correct these issues. For the update to take effect, all applications linked to the GnuTLS library must be restarted. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
