CVE-2026-6103

phar_tar_number() parses the octal size field of a TAR header into a uint32_t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlled file content as the next TAR header, which lets a crafted archive inject entries that PharData reports and extracts as if they were genuine.

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts. The php package contains the module (often referred to as mod_php) which adds support for the PHP language to Apache HTTP Server.

Security Fix(es):

The mysqlnd wire protocol parser reads fields out of server packets before checking that the packet still holds enough bytes for them. A malicious or compromised MySQL server can send a truncated packet and make the client read past the end of the packet buffer, which is undefined behaviour and can crash the process.(CVE-2025-1218)

The SOAP HTTP client guards its response buffer growth with a check that relies on signed integer overflow, which is undefined behaviour and is not guaranteed to trigger. When the check is optimised away, a malicious SOAP server can make the client allocate a buffer far smaller than the data it then writes into it, producing a heap buffer overflow.(CVE-2025-14181)

The parser then skips the wrong number of data blocks and interprets attacker-controlled file content as the next TAR header, which lets a crafted archive inject entries that PharData reports and extracts as if they were genuine.(CVE-2026-6103)

cleanup_xml_node() in the SOAP XML parser recurses once per XML nesting level with no depth limit. An unauthenticated attacker can post a SOAP request containing tens of thousands of nested elements to any SoapServer endpoint, exhaust the stack and crash the process. The same unbounded recursion exists in the SOAP value decoder and in the WSDL node search helper.(CVE-2026-91765)

When the http:// stream wrapper follows a redirect it forwards the user-supplied Authorization, Cookie and Proxy-Authorization headers unchanged, even when the redirect target is a different host, a different port, or a downgrade from HTTPS to HTTP. A server that can steer a redirect therefore receives credentials that were only meant for the original origin. This is the same class of issue that libcurl fixed in 7.58.0 ( CVE-2018-1000007 https://github.com/advisories/GHSA-g7x2-hrfp-pv5f ).(CVE-2026-91766)

php_openssl_matches_wildcard_name() in ext/openssl/xp_ssl.c underflows the length argument passed to memchr() when a TLS server certificate presents a wildcard name whose literal characters are together longer than the hostname being verified. A malicious server presenting such a certificate makes the PHP client read up to SIZE_MAX bytes past the end of a heap allocation. The path is reachable from any default client stream, because verify_peer_name is enabled by default.(CVE-2026-91767)

The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowed_clients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and reaches the FastCGI endpoint.(CVE-2026-91768)

PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN was still accepted when its CN matched the requested peer_name. A certificate trusted by the client for one name can therefore be used to impersonate another.(CVE-2026-91769)

It was discovered that PHP did not properly validate the size of MySQL server packets in the mysqlnd driver. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 26.04 LTS, and Ubuntu 26.10. (CVE-2025-1218)

It was discovered that PHP incorrectly handled response buffer sizes in the SOAP HTTP client. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2025-14181)

It was discovered that PHP incorrectly handled certain TAR archive headers in the Phar extension. An attacker could possibly use this issue to inject arbitrary files into a crafted archive. (CVE-2026-6103)

It was discovered that PHP did not limit recursion depth when parsing certain SOAP requests. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2026-91765)

It was discovered that PHP incorrectly handled authentication headers when following HTTP redirects. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-91766)

It was discovered that PHP incorrectly handled wildcard names in TLS server certificates. A malicious server could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91767)

It was discovered that PHP incorrectly validated IPv6 client addresses in the FastCGI client access check. A remote attacker could possibly use this issue to bypass access restrictions. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-91768)

It was discovered that PHP incorrectly performed TLS peer name verification. A remote attacker could possibly use this issue to impersonate a trusted server. (CVE-2026-91769)

It was discovered that PHP incorrectly handled certain stream filter options. An attacker could possibly use this issue to obtain sensitive information. (CVE-2026-92842)

It was discovered that PHP incorrectly handled empty Location headers when following HTTP redirects. A malicious server could possibly use this issue to redirect the client to an unintended location. This issue did not affect Ubuntu 14.04 LTS. (CVE-2026-93682)
