[Issue 10488] New: Multiple out-of-bounds reads in servers/slapd/result.c v2ref() function
by openldap-its＠openldap.org 22 May '26

22 May '26

https://bugs.openldap.org/show_bug.cgi?id=10488 Issue ID: 10488 Summary: Multiple out-of-bounds reads in servers/slapd/result.c v2ref() function Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: wangxiaomeng(a)kylinos.cn Target Milestone: --- Created attachment 1142 --> https://bugs.openldap.org/attachment.cgi?id=1142&action=edit Fix two out-of-bounds reads in servers/slapd/result.c v2ref() function The v2ref() function in servers/slapd/result.c is responsible for converting LDAPv3 referrals to an LDAPv2-compatible string format. Two separate out-of-bounds read vulnerabilities exist in this function, both caused by insufficient checks for zero-length data before accessing the last character of the data buffer. Vulnerability 1: Out-of-bounds read in text buffer handling Location: servers/slapd/result.c, line 94 (within the v2ref() function): Vulnerable Code: if ( text != NULL ) { len = strlen( text ); if (text[len-1] != '\n') { i = 1; } } When the 'text' parameter is non-NULL but points to an empty string (""), strlen(text) returns 0. Accessing text[len-1] (i.e., text[-1]) results in an out-of-bounds read of one byte before the start of the 'text' buffer. Vulnerability 2: Out-of-bounds read in BerValue referral handling Location: servers/slapd/result.c, line 115 (within the v2ref() function) Vulnerable Code: len += ref[i].bv_len; if (ref[i].bv_val[ref[i].bv_len-1] != '/') { ++len; } When ref[i].bv_val is non-NULL but ref[i].bv_len is 0 (a valid state per LDAP BerValue semantics, representing an empty string), accessing ref[i].bv_val[ref[i].bv_len-1] (i.e., ref[i].bv_val[-1]) results in an out-of-bounds read of one byte before the start of the ref[i].bv_val buffer. Fix Add checks for zero-length data before accessing the last character of the respective buffers. The fix addresses both vulnerabilities with minimal, targeted changes that preserve the original functionality. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10511] New: Add pagesize setting to back-mdb

Add an option to back-mdb to support this.

[Issue 10510] New: write_coherence can assert() on unbind

[Issue 9796] New: Deprecate GnuTLS support
by openldap-its＠openldap.org 20 May '26

20 May '26

https://bugs.openldap.org/show_bug.cgi?id=9796 Issue ID: 9796 Summary: Deprecate GnuTLS support Product: OpenLDAP Version: 2.6.1 Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: libraries Assignee: bugs(a)openldap.org Reporter: quanah(a)openldap.org Target Milestone: --- Support for GnuTLS was added specifically for the Debian (and thus Ubuntu) due to the license objections at the time that the Debian project had for the OpenSSL license. Since that time, Debian has reclassified OpenSSL as a core library and the OpenSSL project has resolved the original complaint by licensing OpenSSL 3 and later under the Apache License v2. Thus there is no longer a reason to maintain support for GnuTLS and given the long standing concerns over the security and quality of the GnuTLS bridge in addition to the extra cost of maintaining that code, it should be marked as deprecated and removed in a future release. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 10502] New: feature proxyauthz should become default
by openldap-its＠openldap.org 20 May '26

20 May '26

https://bugs.openldap.org/show_bug.cgi?id=10502 Issue ID: 10502 Summary: feature proxyauthz should become default Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: lloadd Assignee: bugs(a)openldap.org Reporter: ondra(a)mistotebe.net Target Milestone: --- Most stock lloadd deployments are against OpenLDAP, but since "feature" keyword doesn't allow "off-switches", proxyauthz has had to have been an "off by default" thing. This is insecure and probably a footgun for many. We'll have to introduce a new configuration option to do this, one that allows for gentler evolution. This also allows us to reject a bindconf+no_proxyauthz combinations if we force the rare admins who genuinely need it (no proxyauthz support in upstreams) to opt in explicitly. -- You are receiving this mail because: You are on the CC list for the issue.
