 ------------------------------------------------------------------------- Debian LTS Advisory DLA-3810-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin May 07, 2024 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : php7.3 Version : 7.3.31-1~deb10u6 CVE ID : CVE-2024-2756 CVE-2024-3096

 Security issues were found in PHP, a widely-used open source general purpose scripting language, which could result in information disclosure or incorrect validation of password hashes.

 CVE-2024-2756

 Marco Squarcina discovered that network and same-site attackers can set a standard insecure cookie in the victim's browser which is treated as a `__Host-` or `__Secure-` cookie by PHP applications.

 This issue stems from an incomplete fix to CVE-2022-31629.

 CVE-2024-3096

 Eric Stern discovered that if a password stored with password_hash() starts with a null byte (\x00), testing a blank string as the password via password_verify() incorrectly returns true.

 If a user were able to create a password with a leading null byte (unlikely, but syntactically valid), the issue would allow an attacker to trivially compromise the victim's account by attempting to sign in with a blank string.

 For Debian 10 buster, these problems have been fixed in version 7.3.31-1~deb10u6.

 We recommend that you upgrade your php7.3 packages.
